Let’s see… Which scales better - “Fearing a maw rat kills it” or “Your attacks have a low chance to turn non-elites into furniture”?
The choices aren’t always beneficial to killing the end boss and there are WAY too many of those in the mix. If you get unlucky with Anima Power RNG, you just wasted all that time in Torghast.
Hell, there are a lot of anima powers that don’t even apply and often they are the only choice given. Like Yel’Shir’s Powerglove, which has a stacking buff that makes your next melee strike hit like a truck. That’s a great power to have when you have no melee attacks. Even casters have staves and daggers to use it, but my bow doesn’t count as a melee weapon.
