sage
u'll gain good defensive power from : Tidal( demon one is 50%/ sage 66% , 3spark effect (25% reduce)
U will never lack chi due to many skills giving alot of chi : tackling(0.5), rds(1.80), inner harmony)2) (has chance to give 3sparks) , Master Li (50) , elimination (0.30) and Cursed jail which has a chance to cost only 1 spark if u cancel it , meanwhile demon has/gives less
good offensive skills such as subsea applying 50% effect, Life hunter decreases target maximum hp by 10%
Sage has less dmg on fury compared to demon , but u will definitely cast more often spark, which helps alot in case of rpk/mass pk
