Trapper medal

[Fatt_Shade]

Guard droid hook attack , archmage telekinesis ability , green dragon grab ability , or try this : (spoiler) take some strong unit to deal with enemy and then take 10 inquisitors (split them in 1 + 1 + 1 + 7, 5th slot is some dragon best). Let dragon kill enemy but leave some weak range stack alive and then use trap 1st lvl in front of your inquisitor , move him on trap to die it will count for medal and give you lots of mana from transmutate skill in magic tree if you took it. Then revive dead inquisitor with some of others and repeat this as much as you can (you can get 3rd lvl medal in 1 battle with this). But dont kill stack of 7 inquisitors because on them you cast phantom when you use revive on other 3x1 stack.
Try it out on some weak enemy to see how it goes.
