Has anyone tried using the Carver Shadowstalker (“CS”) as a tank?
The idea would be to give it an artifact with speed enhancements (or Topaz Focus on another creature) and the Blood Dance legendary enchantment (the ability of the Witch Doctor Sacrificer). If I understand these abilities correctly, the high-speed CS could start each round by defending, which triggers the Blood Dance ability and makes all other creatures take only 1 damage from all attacks. Normally this would make the CS highly vulnerable due to the 100% damage increase from Blood Dance, but defending would also trigger the inherent Cloak and Dagger ability of the CS, meaning that it gains Invisibility each time and never loses it (because it never attacks). Since Invisibility makes it impossible to target the CS with attacks or spells, and all other creatures take only 1 damage, it would effectively make the party invincible.
I lack the materials to actually try out this tank build, but any thoughts on its weaknesses? Maybe splash damage and other group effects? Stun, etc. that would keep the CS from defending each round? Something else I am missing?
