Magmaback Alpha is a bruiser construct miniboss. At the lowest Threat it has 900 health, hits for 28 and carries 10 armor. It moves at 3.2, can reach you from 2.4 away, and telegraphs each swing for 12 ticks before it lands, then waits 24 before the next one.

It fills the Miniboss slot in Cinder Forge.

Killing it pays 80 XP, and it drops something 50% of the time. Crowd control lands on it as resistant.
