Grimstroke is a forceful support and nuker who pressures enemies with an array of punishing spells. He creates dilemmas for his opponents, compelling them to choose between attacking or retreating. In addition to inflicting heavy magical damage, he can also Soulbind two enemies together to make them suffer damage and disables at the same time. As for his weaknesses, Grimstroke is lacking in mobility, and can burn through his mana very quickly.

It varies depending on how you lane, a very situational hero that I'm in love with currently and hope to top charts with in the nearest future. However, minor hints I can give you is that this hero will probably be like a double edged sword and things may go very wrong by mid-late game if you don't do things right, mainly because the hero isn't very tough standing on 2k+ health on level 25 isn't so high and is squishy on the armor/resist part. So I suggest doing some testing/tweaking around with item builds and be creative around how you will handle situations throughout the entire game's phase while playing this hero on whichever role you choose.
