Getting the Trap medal is easy , specially for a mage.

As a lvl 29 mage I wasnt missing the trap spell yet, mainly because of the Ancient Phoenix. But knowing how helpfull it is, I went and did 100 kills in a single battle going from nothing to lvl 3 trap medal.

Want you need is Transmute at lvl 2, the spell Phantom, the rage skill Mana Accelerator and a few stacks of Inquisitors. Make sure 1 stack consists of only 1 Inquisitor.
I used 4 stacks of Inquisitors and 1 stack of Red Dragons. But I should have used 3 stacks and 1 paladin stack plus the dragons.

Pick a battle where there is a archer type unit and leave few alive at the end of the battle.
Then cast Trap and let walk the lonely Inquisitor on to it. After its dead resurrect it with other Inquisitors. Killing the Inquistor will give 10 / 14 / 20 mana depending on your Transmute skill. This will help pay for the phantom spell to clone the Inquistors. Use the Holy anger to fill up rage and Cast Mana Acceleration. I used the 16 rage = 14 mana. At lower levels use the 11rage = 10 mana. Paladins help to make full use of the Holy Anger. With a bit of luck you should able to continuely keep killing the Inquisitor / resurrect him / phantom Inquisitors / Holy anger / Mana Accel.
