These are MoM Global spells not previously suggested I'd liek to see in WoM.
Crusade
Life / ?
All the caster's living units gain +1 level while upkeep is paid.
(Keep tracking experience so the units will remain at max level if they have earned it.)
MoM had some interesting high level spells which made automatic dispel attempts on a specific spell domain. We should have one for each element for sure.
Life Force
Life / Protection
Any Death spell cast by an opposing Wizard has a X strength Dispel cast upon it. Existing enchantments are unaffected. (Actually it worked more like a barrier. Instant spells would fizzle too.)
