So, here’s the deal with Inner Fires and healing. Inner Fire removes the post-battle healing cooldown only if your dragon took absolutely zero damage. This means:
Never took a hit
Never used an ability that hurts or kills the dragon
This doesn’t mean:
Took damage but healed (healing is not negating damage)
Was killed but came back (you definitely took damage)
If you correctly meet the criteria (you used inner fire and never took any hits / damage) but still had a post-battle healing timer, please send in a ticket with the date / time of the attack as well as who you attacked and the dragon(s) you used.
