[3.1] Poet's Pen Volatile Dead dual curse Inquisitor || Budget friendly under 2 EX || Shaper down

Skilltree shows that you use 4 jewels. Which one do you use respectively what mods would you recommend?
Anything special apart from the often strained Watcher's Eye.

Hey man, sweet build, but I notice your "Cast when Damage Taken" support gem says "supported skills deal 6% more damage" but the one I have says deals 46% less damage.

Is this mechanic broken, or do I need to get it to level 20 to get the +6?

Thanks
