I also got it stuck at 28 % :

Unkillable Dryax at Colosseum after today’s client update: after I kill one the second one becomes “immortal” when 28 % damage is reached - after that damage/score is incremented by 1 no matter what you do. I’ve tried two battles, restarted the game, tried third leaving on auto for about 10 mins and could only get to 29 % as a result.

Same here

Same here, and I didn't want to leave the screen because I got a new record.

Ally code: 883454867

It's ... so unfair.

Not even right that both below their 50% are totalling a 21% of the level.

I was stuck at 36 % and same thing...any hits are only 1 point on score. I was playing and went to bed because it was taking so long. Woke up hours later and the battle was still going!
