Yes, Army of Leaf. I am eco friendly you know, and backed by Pangaea. My favourite temperature is Cold 1, and it's currently 32 C in my room, so I blame any and all typos on the heat.

Slen: glad you like typos just as much as I do (you go to the jeweller to buy germs, while I use leaves to forge something). The AI will automatically use extra gems, if some are to be found, depending on the situation: the AI will especially use some to cast very tiring spells and/or against "powerful" foes.

The first extra gem can be used as a +1 magic boost for that spell online, and all other gems are used to reduce fatigue (as though the spell was cast by a mage of a higher level). Note, however, that gem usage cannot go higher than the real level of the mage, and that includes the non-extra gems.

So, we have an Earth 8 mage wanting to cast Army of Gold, a 600 fatigue spell (it therefore requires 6 gems). The mage casts Summon Earthpower, bringing him to Earth 9, and then casts Army of Gold by using 9 gems. 6 of those are used to cast the spell, and the 3 others are used to improve the spell. For this spell, our mage is effectively Earth 10, and will have the same fatigue as a level 12 mage casting this spell (100 fatigue, if I am not mistaken).
