2.41 patch, Ninja nerf for the Ninjas and Dungeons.

[kyuven]

again, no its not. the dmg potency is what it is. the only version of the game that mentions positional is the english version. all other languages do not have "requires flank".

which is exactly why i said they'll either change the ability to match the english version's description, or change the english version text to match the other language's text, depending on what they actually intended
It could be a very clever way to hedge their bets and have it not come across as a nerf after all
