Modded spells and AI

[Twan]

My impression is : modded buffs get an huge priority, and the AI doesn't recognize them as non cumulative.

(ie : I've made a spell using legion of steel + barkskin + resist fire + cold aura effects* all being non cumulative, and the AI often chain cast it several times on the same mage for no additionnal result ; or use the component spells in addition)

Personnal spell made mass buff spells may also be affected (or it's perhaps just a result of one or two units to affect ; also a problem with non modded spells). AI casted several time the "Mass Glamour" spell I've made to replace MoD** in my test, just to give mirror images to one or two units who lost them.

Perhaps (I hope) there is something (still undocumented / not discovered) to add in the #spec field to make the AI recognize a spell as a "one time only" effect or reduce the priority it gets ?

If not I have a suggestion : make any modded spell using effect 10 or 23 (buff) "cast only if scripted" by default.
It's sad to see some of the rich possibilities in magic modding unexploitable because they make the AI dumber (now as buff effects weren't documented in modding.pdf, new buff spells aren't supposed to work well, but it would be cool if possible).
