I know this issue does not happen often, but it happens to me.
I have two Onatels @ max level and skill, and when I use both of them on 1 team, I think their special skills do not work correctly.
I think that each Onatel should have her own special skill tracked seperately, this includes the Mana stealing over 4 turns countdown, and also the Recovers 4% health for all Holy allies for 6 turns countdown. This would double the health recovery to 8% for all Holy allies because each Onatel cast her own special skill.
What happens now is when the Onatel1 casts her special she gets a countdown of 4 turns Mana and 6 turns health, and then when two turns go by and Onatel2 casts her special the countdown resets to 4 and 6 for both, instead of staying at 2 and 4 for Onatel1, and 4 and 6 for Onatel2 , and Onatel1 does not steal all the Mana generated when her countdowns would have reached 0 and 2. Also the recovery stays at 4% health and should be at 4% for each Onatels special.
What do you think?
