“Holy Aura” Ally troops gain +5% accumulative resistance to all negative effects. EX:Turn 1 remove death mark would be at 15% instead of 10% and etc
“Unholy Aura” Enemy troops lose 5% accumulative resistances to all negative effects. EX:Turn 1 remove death mark would be at 5% instead of 10% and etc.
“Defile” Refresh all current negative effects on enemy troops on 4-5 gem matches
