Sell me on the idea of Penombre Alright.. so im to the point in the guide where it says to max penombre... but i dont get it. its as skill I barely use and it seems difficult to control.. also slow. is there something im missing? because i dont see why this is more important to max than both mille and tempest (2 skills i regularly use). could someone please sell me on the skill of penombre and when i might possibly use it?
