Tactics for the Swamp (Fortress).

You can find a use for Water Magic and level 3 spells too (I once broke through a GO with Force Field), but that's not a common occurrence — it's more of a "once in a blue moon" thing, IMHO. For every Scout with Expert Water Magic (zero versatility, by the way — Liches and Elementals don't care), there are 10++ with Haste/Extra Serpents/Expert Armorer. Has anyone here had cases of using it, I mean, intentionally?
On Jebus Cross, it's a real example, it's just that Earth and Air magic are chosen and utilized much more often.
