I mean I did get it last Breath when I had all the other useful skills purchased, but looking at it now, when I'm close to maxing but missing CP from Exploration badges/bosses - it looks not even like a niche skill but a really bad artifact from times when anti-Defiler's poison was valued very highly.
Considering Stamina is 20 CP and gives 10 HP, let's be generous and say 40 CP for 20 HP is fair at T3 (it's not IMO - comparing to Fiendish Bulk which does a lot more for 60 CP, but OK)
Can we change it to something else or lower the costs? Or remove it entirely so I'm not sad looking at it
