Tornado + EMP + Coldsnap is your first skill combo's. that allow u to have good damage output and an annoying manaburn + stun for ur opponent. Quite Good for fight but better for single target ( I do not like to use tornado in teamsfights except for retreats or to hit enemies on the run)
Defeaning Blast +
This combo makes a lot of damage (in late game, when ur exort lvl is high) and is good to engage a team fight.
Good combo for late game(when ur exort lvl is high). it can be some kind of permastun for ur opponent.
forge spirit make a lot of damage, and their armor reduction ability is helpfull against a tank character. (usually i use it with exort buff just to have more damage output).
variant for coldsnap + forge spirit
This can be lethal if u master that. forge spirit with their armor reduction abilities + ur alacrity buff and cold snap on 1v1... probably the enemy will not move from his position 'cause of the stun XD.
can be also usefull if casted on a carry in teamfight or on urself if pushing a tower.
This can seve ur life if used at the right moment. that will slow a lot ur enemy allowing you and ur allies to run away or giving advantage in combat.
