I was tinkering a lot while making Crypt, few more ideas:
Cultist:
- Damage: 1d6
- HP: 18
- You sacrifice 3/6/9 HP to summon an imp. It has 3/5/9 HP and 2/3/4 damage.
Plague Doctor:
- Damage: 1d6
- HP: 18
- Once per turn roll a dice. Deal that much damage to everything except Plague Doctor. Summon that many 1/1 rats.
Barbarian:
- Damage: 1d6+2
- HP: 20
- On kill: Attack again.
(haven’t played with yet) Vampire:
- Damage: 1d6
- HP: 18
- Regain half of the damage dealt as HP.
