Ghastly Band
Shadow Isles -
Unit 
Hallowed:
After I die, for the rest of the game when allies attack, hallow your first attacker giving it +1|+0 that round
Ephemeral:
This unit dies when it strikes or when the round ends.
Their repertoire was impressive, from minuets and waltzes to ballads and folk songs, but truth be told, the party's guests were dying for something new.
