A neat trick
Pressing one of the "F" keys (F1, F2 etc.) brings up the "Cast Spell" list for the corresponding character. However, if a slot is empty, it brings up the spell casting menu of the last character to occupy that slot. So, place your Archmage in slot seven, then remove a character. Slot seven is now empty, so you can press F7 to cast any Archmage spell you like, without wasting spell points (actually, the 'character' that is sitting in that slot has a finite amount of spell points... you just can't see how many there are. Doesn't really matter, when they run out, cast INWO and repeat the above process). It doesn't work in combat, but is handy for just about everything else.
