This hero is versatile, being a melee that has a good passive to tank harass I could see this being an offlaner or just a 4th position support with another tanky offlane. Roaming with this hero as a support would also be very good and a smart skill build will allow you to use his full kit.

At level 6 his ult is excellent for disengaging or turning a fight, the pyramid making him un-targetable for 1 second. In the later stages in the game, he can dish out as much damage as other cores but his limited mana pool leaves him susceptible to mana burn heroes and reliance on blink to get a good ult off is an issue most heroes offlane initiators have.

Summon Obelisk
- Blocked by Linken's sphere
- Reflected by lotus (Although why would you?)
- visibly begins erupting from the ground
- fissure and other landscape-altering abilities do not move pillars
- Stun only affects the unit you target/ just one unit closest to the obelisk

Geomagnetism
- Similar to drow's knockback but a smaller width
- Multiple obelisks only refresh the current duration of root, not stack.

Stone Control
- Each stack blocks up to the current block then shatters for the same damage as an obelisk
- The obelisks glide and movement can be interrupted when either one is destroyed
- You can click yourself then another pillar to glide to the pillar if your Armor is destroyed while gliding it does not stop.

Stone Pyramid
- You are Invulnerable while the Pyramid is active
- fissures do not go through the pyramid, but the wall is there when the duration ends
- You are petrified after knockback not while being knockback.

Pre Level Six
You would prefer to start with (Q)Summon Obelisk, making sure to be behind the hero you wish to gank if possible, then follow up with your (W)Geomagnetism for a point-blank root. This should give you enough time to hit another Q and if the hero isn't killed yet you can always chase him with (E)Stone Control. When anything goes wrong escape is difficult but you can tank a few hits with a level 1 E, or if you saved an obelisk from the first Q you can always use that to get further away.

Pre Blink
The same combo can apply, but in most games, the mid-game makes it very likely for more than one hero to be in the same place. A way you can compensate for this is to start with your Q out of vision and then follow up with your E instead, this would remove your escape but get you to a better position to use (R)Stone Pyramid. If you are skilled enough and time it correctly you can get a Q and W combo off before any counter ganks can happen.

Post Blink and Late Game
Starting with your Q is virtually impossible against heroes with blinks and force staffs unless your enemy is blind or doesn't notice a big-*** Obelisk about to erupt beneath them. Blinking in and then casting your R is the easiest way to initiate a combo, then follow up with a Q-W combo, if the enemy has a BKB I would suggest to summon an obelisk away from you instead and to E towards it and disengage.

In a 5v5 team fight scenario, this hero would be best used as a counter initiator or follow up lockdown to something like an RP. I don't think starting a fight with a Blink R is the best idea, although possible if your team has no other massive team fight ultimate or have much more important ones to save.
