My plan is to just slap on:
+ Power Range - Power Strength
+ Power Efficiency - Power Duration
+ Power Duration - Power Range
And one spot for either Quick Rest or Constitution, depending on situation.
So, you get:
+24% Power Range
+75% Power Efficiency (with Essence) (CAPPED)
+39% Power Duration
-60% Power Strength (does not affect any of your skills)
+1 empty slot for a mod of your choice (potentially another +28-30% Power Duration, if you so please)
You don't see many builds out there that offer this level of bonus with capped Power Efficiency. If you want to use every single one of your Abilities to their fullest extent with perfect Efficiency, with no downside, I recommend going with this one.
I like it muchly.
