Limitations of the Tactic
- Feats: Using DMM Persistent requires that you invest at least 3 feats (probably 4 - extra turning) into the trick. Feats are a precious resource for most clerics, so this cost is not inconsequential.
- Ability Scores: This requires a CHA-focus. Clerics are a fairly high MAD class so this is a sacrifice, assuming standard point-buy for ability scores.
- Dispel Magic: A simple Dispel Magic can wipe the buff away, making all those feats and turn attempts and equipment worthless.
- Uses Turn Undead Attempts: While turning undead is usually pointless, sometimes it is handy. Some days a cleric might prefer to have turn attempts left than to have Divine Power running.
