Grace skill gem

Grace skill gem went from 50-80% mana reservation its not linked. THe skill gem should be 50% mana Base. I do have some talents for mana reservation. I noticed the bug after receiving second wind (lvl25) on my bow (cruicble event). After swaping the gem to another item its still keeps the increasing the mana reservation.

The gem was in the bow when i upgraded the Cruicble perk(weapon skill). I tried swaping it around with other green slots in my gear to see if it would help. The tooltip is reading 80%. THe skill gem is reading 50%

not a bug.. you have it supported with a support gem/crucible support gem mod.

if you want it to cost 50% put it somewhere where it isnt linked to a support gem.
