Which is better, Knight or Serpent Cataphract

[Xietor]

I think it is a bug that the serpents disappear after combat.

Machaka's spiders do not disappear after combat. The poison does 20 points of stun damage(fatigue)(thanks Dr. P). Makes it situational. I would rather see them do just strong poison, and I would like to see the serpents stay after the fight like the spiders do.

Spider riders also are not immune to poison, but the spiders are. Serpents should be 100 percent immune to poison after the rider is dead.
