I would like to suggest that tier 3 altars also be given the characteristic of setting it as a respawn point. Only altars that are in your alliance. Only one altar of each type can be selected.
So on death, your options would be:
- Mitra Altar
- (The other not listed in feats until you discover and onlock it)
- Dungeon, should you happen to be in one
Honestly, altars seem more logical than beds. Returning from the dead seems like a religious experience, more than something you just “sleep off”.
