0.10.12 still can't kill Head of Loid

It already resurrected its body parts like 10 times already. As you can see, the fatigue ran up to seven million percent, yet in the Battle History, I couldn’t find any mention of Head of Loid ever taking any damage. Notably, the Shelled buff sat on the head the whole time, maybe that has something to do with it?

And another one:

The only possibly relevant runes that I can recall being effect were “20% chance to avoid damage” and “Immune to spell damage”. The rest were stat bonuses, and inflicts 3 debuffs.
