I had 2 unarmored slingers in the front, to catch his breath, which is pretty useless anyways.
one prophet nearish the front, who divine blessed then mixed up smites and sermons.
one mictlan tribal king, w/ a purchased vine whip, and 2 jaguar guards, on one side.
7 jags on the other.
The vine whip only hit twice i think, but still helped. The morale on the jags varied widely, from 8 to 21 i think, due to sermons and the draco lich's +12 fear (also awe +2); but they mostly held.
Draco had 180 base -36 for dominion -36 for neverhealing wound, for a total of 138 hp (

). he was not crippled; chest wound does nothing.
Pounded on him w/ large sharp-edged chunks of obsidian until he retreated into *poof*
the king and his guards had broken, but the other 7 were still in high dudgeon.
one brave slinger gave his life for his god and nation.
The key to this was to deny the beast his attacks. The vine whip helped, but mostly it was the Twist of Fate on the Jags, especially as the AI does not prioritise units who have already lost their Twist. So damage was minimal, and did not feed into loss of morale.
