Is the Realm 31 Boss Beatable

[Horth]

I am in a stalemate with this boss. Each turn I do 160 damage and it heals for 125-250 damage. I am mostly at full health with all my creatures. I've been battling for 30 mins. The boss gained 2 Million Max HP on the last round. That gain doubles every round. All I see is that it is dying, but it would say that if it had 1% HP left from a Max HP of 4 Million HP, or 40,000 HP left.

What % HP does Dying represent?

Perhaps I need that Spell that sets its HP to 1.

Bosses have random spell gems just like every other enemy. That fight's mechanics make it more random than the rest of the bosses, just try again.

[Horth]

Thanks. That worked.

I found that the Spell Gem of Brain Freeze very useful in this spell only fight. It prevents boss and lackeys from going into 3 minute spell routines because it permanently disconnects them from their spells so all they do is defend or rely on traits/artifacts

Now I wish I had used brain freeze in the fight with the necromancer, I was spending a lot of time playing whack-a-mole with his summons before I could damage him.
