I am using burn to take down boss. It all goes very well and I can pair Tyrant with at least 3 of my champs to do it in about 3 mins. But when the dragon is at 10% he "magically" gets super resist that make it so my burn doesnt stick. But there is nothing in his skillset that increase resist at 10% hp left!! Nothing. But still my burn then can't stick. So he heals back up to 20-25% HP. Then I can burn him again... and below 10% there is no chance!  I even increased accuracy to see if it helped, but nope... he still "cheat" somehow!  

please fix!!
