I think I'm stealing this from another post, but I can't find it. The current Altar of skulls is so balanced(to the point of blah) and takes forever to start. I don't like it, so here's what I imagine. I welcome you to tell me why its broken.
Same everything as the current altar of skulls except:
1)Destroyed Friendly Living creatures add a skull token (including with sacrificial altar)
2)Clerics can add a skull token: Cleric spends a full action (in any zone) and destroys a friendly living creature in that zone(which could be himself). This adds 2 skull tokens in total when you include (1).
3)Clerics cannot "pray at altar" to add a token
4)I would be open to enemy nonliving creatures NOT adding skull tokens
Yes, you can get the altar fully operational in half the time, but it requires your necromancer to spend 4 full actions summoning living creatures that have to die. the altar costs an extra 20 mana in sacrificed clerics.
Synergy:
zombies pyramid and killing your own living creatures
reanimate has a stockpile of creatures to draw from
now go ahead and tell me how my idea is awesome.
