You really have to time attacks with afflict, poison, stun, etc, so they happen early in the round. That way he misses his healing opportunity before Llama gets to cleanse.
I haven't seen it in action yet with this particular combo but I think the deathblow ability can help counter this. I've seen it work in other battles and even without buffs I think it would have a decent shot at leveling the playing field in this scenario.
In the meantime just have some !BEER and !PIZZA !BRO
Just because Llama and Kron got no !LUV for you doesn't mean all is lost 😁
