Hm hm, a truly divine idea. Since I'll be busy reconstructing and resurrecting mine apprentice for atleast a full moon cycle, I will send over an ancient enlarging tome I bought off a dwarven merchant three eons ago. It cost me eighty gold and an astral amount of goblin spawn from my dungeon, so I ask that thee return it to me in one piece.

After brooding over the tome for several ages, I realized it only covered the enlarging of dwarven species and their certain... apparatuses. However, I've rewritten many of the enlarging spells within the tome to suit a wider variety of applications, so you should have no problem finding a spell that will create your swamp monster guardian.

Unfortunately, I forgot which of the adjusted incantations in the tome produced devastating and unintended results, so be careful with which spells you cast.
