Kurthifa the Crimson Knight by Cuttleboss

+ Excellent starting stats between attributes, armor, regen, and movespeed, very powerful hero from early game
+ Low mana dependence as only one spell costs mana
+ Low cooldown skills, does not have to play around cooldowns
+ Good mobility between two spells
+ Potentially very high scaling damage output with both right clicks and nukes
+ Has very easy and early access to heal reduction
+ Activates with only a bit of farm and stays a huge threat into late game
+ With some items and levels she can be extremely hard to kill
+ Easily one of the hardest heroes to manfight and comfortable in the frontline
- Extremely item dependent throughout game, needs to stay farmed to be useful and is inflexible in role.
- Very level dependent and reliant on talents, needs multiple levels of skills for them to be powerful
- Mobility spells are soft mobility due to either short distance or not being able to bypass terrain
- Very vulnerable to Break and burst damage, especially scaling burst damage.
- Needs to be at low life to farm quickly and deal damage, meaning it’s much easier to get nuked or disabled to death than other tanky heroes
- Requires key synergy picks (like Dazzle, Oracle or Io) to be optimized

Kurthifa is a carry that needs farm and levels. Because of how powerful and fast she is early game with her high damage boosted by her passive, the general usefulness of Run Through and the escape capabilities of Crimson Impact, Kurthifa is well suited as a midlaner. She can easily wear down most opponents with many uses of Run Through and can out last-hit them with the damage from Mortality Rush.

She can also be played as a carry in a sidelane and this is where her Crimson Impact shines more, as she can gain more attack speed from facing multiple foes. With the right partners she can stomp the lane with her huge damage output. Either way, her gameplay is mostly aggressive, as she wants to use her innate high damage, speed, armor and regeneration combined with her mobility to bully whoever she can. With her gameplay however, it can be very easy to overcommit to plays and end up feeding a lead. In terms of gameplay, she would be like a Huskar, Ursa or a Legion Commander as a carry and burst damage hero that activates pretty fast. She is not this super fast farmer but she hits hard and can be very hard to kill and puts a lot of pressure on enemies.

She can also be played as a utility position 3 hero built around regen reduction and disabling with her Run Through and nuking with her Retribution, however she is much less optimal with standard aura items than most tanky position 3’s due to only getting huge value out of strength and health. This type of build will probably just be more gimmicky and fun, but situationally could be strong. As a utility she is more like a Night Stalker, having tankiness, spells, and attacks to deal damage and pressure enemies.

Kurthifa has a low skill floor as all her abilities are simple and she is mechanically easy to execute. She takes a lot of practice to master her low-health based decision making, so it takes a lot of practice to master her. Because of this, she has a low skill floor and a medium-high skill ceiling.

Item Discussion:

First Damage Item:
Armlet of Mordiggian: Probably most reliable first item as a damage dealer as is pretty common on strength cores, but very strong on Kurthifa due to how her passive works. This item can also be used to keep her health lower to get more damage, though with the Mortality Rush toggle, it means that it is not entirely necessary to get Armlet to keep health low.
Shadow Blade: A less damage but more of an impressive ganker item, Shadow Blade allows Kurthifa to get kills all over the map by positioning well for Run Through.
Battle Fury: If for whatever reason you decide to build Kurthifa as a farming hard carry that builds around her Crits and buying lifesteal, this item fits her, as she has built in damage, can cast crit, and has mobility spells to clear camps very quickly.

Minus Armor:
Assault Cuirass: A very good and balanced item on this hero, massively increasing the value of her hit points. Should be a big priority in late game in carry builds. Pairs well with Desolator.
Desolator: A powerful item if bought reasonably early, this stacks well with Assault and the hero’s level 25 Armor Corruption talent.

Utility:
Spirit Vessel: A great option, stacks with the regeneration reduction of Run Through. Makes her a huge anti-healer threat.
Heaven's Halberd: Useful against key enemies and generally makes the hero very survivable. Probably a legitimate option even on the carry build of Kurthifa.
Solar Crest: A good item for utility Crimson Knight, as it makes her tanky but also allows her to do some physical burst damage with the armor reduction.

Mobility:
Force Staff: As Run Through allows you to drag the latched hero, you can use Force Staff and Crimson Impact to significantly displace your Run Through target far from the enemies. Useful in general as a utility hero with certain matchups as well.
Blink Dagger: If played like an initiator, Dagger allows Kurthifa to jump enemies with Retribution's stun (and significant damage, even if cast from full health) and then use the other mobility skills to flee, disengage or chase.

Nuker:
Kaya and Sange: Boosts the damage of Crimson Impact and Retribution on two fronts with health pool and spell amp. Also makes Kurthifa much harder to kill.
Aghanim's Scepter: Adds 1000 to the cap of Retribution, makes the potential combo damage much bigger, especially with Adrenaline Burst.
Ethereal Blade: Can massively boost the damage of Retribution, making it one of the most powerful nukes. Its own nuke scales well with Kurthifa’s high strength too.
Dagon 1 to Dagon 5: It’s Dagon. 3 guesses on how it synergizes with the Nuker build.

Tank and Status Resistance:
Sange and Yasha: A good all around item, the speed helps with kiting and pairs excellently with lifesteal.
Satanic: A huge damage boost for Kurthifa, and the status resist fits well on her too. With Run Through's crit, the Satanic active is an effective way to heal to full.
Heart of Tarrasque: This is one of the best potential damage boosters on this hero, as it gives you more health and survivability which boosts 3 skills. However, if you do not use your Mortality Rush toggle, it will keep you at full health and will massively slow down your farming potential, so be mindful.

Kurthifa’s skill build is flexible and offers many options on how to play her.

Crimson Impact is a good spell to have during the laning phase, as the lunge distance is consistent it only needs one level in many lanes. In lanes with multiple enemies the extra points are valuable for a higher amount of attack speed and overall damage since in one on one, trading 20% of your health for 8-14% of it in damage on one enemy is underwhelming. Otherwise this spell would be maxed last, as it is a lot more useful as there are more teamfights and Kurthifa has more health.

Run Through is a powerful skill to have as a value point, as it does a lot of things and is your primary disable. It is the preferred spell to max in 1 on 1 lanes because the crit is useful as a nuke and it is your only spell that costs mana so you can spam it many times to crush your enemy in lane.

Mortality Rush is potentially a very strong skill. It grows a lot stronger as the game goes longer, but offers a fair amount of use early game in laning, as it can easily provide 10-40 more damage for last hitting and denying. The spell may be worth putting additional levels in if the enemies have less nukes and disables as it can allow Kurthifa to maximize her damage output in the lane. Normally however, it would be maxed second or possibly third.

Retribution is a huge power spike and should be skilled whenever you can. There is no reason to wait on increasing its level, as the health cost does not go up.


Talent Choices:

Level 10: Health vs Lifesteal. For Kurthifa, Health pool is more potential damage with all her abilities while Lifesteal gives her an impressive ability to go toe to toe with many early activating heroes at that part of the game. The Lifesteal also has strong synergy if she is buying an Armlet as it will give her sustain.

Level 15: Health Regen vs Attack Speed. This is another sustain vs damage talent, the health regen can be useful for sustaining if you are not relying on lifesteal, as Retribution and Crimson Impact deal a bunch of damage to Kurthifa. The attack speed is straightforwardly good for farming and fighting in general.

Level 20: 2 Run Through Charges vs Double Mortality Rush damage. Run Through offers more disable, escape, and potential burst damage with the critical hits. The improved Mortality Rush is a massive boost to damage. For the most part, this one is utility vs carry.

Level 25: Armor Corruption vs Retribution Stun. Armor Corruption fits well with Impact, Run Through, and Mortality Rush and can be incorporated into an armor reduction strategy or draft. Kurthifa is very strong if she can bring down the armor of her foes. The Retribution Stun is very useful in nuker and utility builds to disrupt the enemies and becoming a very annoying disabler and is much better if you are not the main carry.

Ideal Allies:

Last Chance Hit Point Heroes:
Heroes that allow Kurthifa to stay alive at very low health and able to output her peak damage for a while. If she has lifesteal she may even make a recovery (though not with Wraith King aghs).


Aggressive Combo Heroes: Healers are extra good here as it allows Kurthifa to keep moving forward with her mobility spells, but essentially a hero that helps Kurthifa play aggressively early game in lane can snowball her hard. A lot of initiators count here as well.


Armor Reduction: Kurthifa is a hero that is natural as an armor reducing hero. These synergistic picks can make her a massive threat through the midgame and lategame.


Damage/Speed Boosters: Kurthifa likes heroes that make her attack faster or hit harder. She has a lot of strength and it does not inherently provide huge amounts of damage. Damage boosters make her less reliant on being low on health to use Mortality Rush.

Good Against:


Man-Up Heroes: Manly as many of these heroes are, they are at a disadvantage in close combat against Kurthifa as she can fight them to low health, can suppress the lifesteal or regen they usually rely on to fight, and nuke them for huge amounts of damage as she gets low on health. Even if they are stronger than her, she can use her two mobility skills to disengage.


Short Ranged Agility Carries: These heroes are usually at a disadvantage against Kurthifa. She is tanky and thus hard to DPS down and having a nuke that she uses when she’s low on health lets her overpower most of these heroes. She is good against evasion (as all her spells pierce it) and is a good armor reducing hero (which counters most of these heroes), which nullifies a lot of standard agility carry tools.


Mobile Heroes: As Run Through has a latch and a root, the Crimson Knight can counter these heroes by taking away their mobility and leading into bursting and stunning them to death with Retribution.


Lifesteal, Healer, and Regen: As Run Through provides a powerful regeneration suppression aspect to it, many heroes that rely on huge amounts of regeneration or lifesteal get hurt badly by it. A lot of heroes that benefit from these types of skills (like DK, Necro, and Timber) also counter Kurthifa however, as seen below.

Worst Enemies:


Damage Dampeners: These heroes weaken Kurthifa’s damage output, which limits her ability to tear apart her enemies. Anyone who applies Break also applies here in the same manner as her passive is the source of most of her attack damage.


Root Kiters: Most slowing based kiters are not a threat since Kurthifa has Crimson Impact and Run Through where she cannot be slowed. But root based kiting is a nightmare for her and often can lead to her death as she will not be able to use two of her spells its almost akin to a silence.


Scaling Burst Damage: Kurthifa has a lot of health in many of her builds and as her health gets lower she gets more powerful. Many nukers can blow her up before she does any real damage and generally she eventually counters them as her health pool gets larger, but ones that scale will be able to do so even into the late game. These are some of her biggest threats.


Low Health Killers: Similar to the scaling burst damage, these heroes specifically counter being low health. They finish her off before she can do her best work at low health.
