Battle script substitution?

Ah, I did not realise that you could Fanaticise/Sermon more than once on a unit --- I assumed, like a buff, there was a one-time raise of morale and no possible re-affectation.

When you banish, can you accidentally (by missing, or via AoE) banish your own undead (I assume you cannot accidentally bless/sermon opponents)? Banish does not have the 100 Precision of other holies.
