Possibly a defiler does not have to drain nature - although he would do it as his preferred source of energy, he could also (at least for minor to moderate spells) rely on "conventional" energy sources. This would prevent Echo's solution being used as the defiler would just refrain from draining nature for the simple spell.
It has potential, but a bit more work is needed to make it actually workable. 2/5 Go to Comment
I think that the congregation of the different nature religions for a great festival of nature has more potential than hunting down a defiler mage hidden in their midsts. See Echo's comment on the easy solution.
It would be more interesting to know why the festival has come into being, what occurs, why the people attend, and so forth.
If it is known that one of them is a defiler, have all cast but a simple spell. So easy. "Cast a spell to prove your magic ability, so that you may continue with the contest."

A festival of druidic rites and initiation rituals, either old-school or new-take, perhaps with this basic concept but with all the juicy and necessary details, would make a fine sub indeed actually! Go to Comment
Mages/ wizards and such use cards (playing cards or tarot cards) as training tools. The patterns created by certain layouts of cards are mnemonic devices to teach key elemental associations and paths. With such interesting names as the Tree of Life, Phoenix's tail, Rythm of Heart, and Balance of the sphere, there pattern represent the matrices used by magic users to focus and present power. Spell processes can be represented by a sequence of cards.
So mages will often be seen handing around hands of cards.
Wizards will have a deck of cards with them. Since cards were used to train wizards in legerdemain, Since they have cards with them, they frequently know how to use them. Guild magic users often have a knack for fancy shuffles, palming cards, and a variety of card tricks and games.
