Falling frost vs. AI hordes

[Meursy]

Whoa, a _second_ mage? Yeah, teleporting a lone mage in to cast Rigor Mortis or whatever without any backup is definitely not going to work, though I guess you've worked that out on your own, which is cool. The battlefield wide damage/fatigue enchantments are simply not that powerful afaik. The level 9 evoc spells might work like that though.

I'd be sending in at least two extra mages to spam the elementals, make sure you give em enough gems to cast for two or three rounds, including a few extra to suck up some fatigue. Boosters to get you above the minimum level you need for the spells will allow you to cast longer before fatiguing out if possible.

You could also send some mages to cast other battlefield summons, Rigor Mortis combined with a couple of Undead Hordes followed by skellispam could work.

If you don't need to teleport/trapeze, consider handing out some flying boots to these guys instead. Also give a scout some flying boots and replacement gems, and your mage hit squad can terrorize your opponent for several turns, not as easily/cheaply as a flying thug/SC would but still usable.

You can also just bring regular bodyguards if you use Flying Carpets. And Bottles of Living Water are always an option for self-replenishing mage protection, in and out of battle.
