A mod were you craft Wands to do different spells from the harry potter series would be Awesome, like two sticks on top of each other, then like a diamond on top for one spell, or a gold ingot for another. Who knows, maybe even add NEW items to craft each Wand? Also could add new Potions, Such as Felix Felicis (Liquid Luck) Which makes all mobs attacks miss, no falling damage etc for a limited time. Could add new blocks, or Mobs; like ghosts, 3 Headed Dogs (Cerebus') or Dragons etc (I know The ender dragon already exists, but maybe a dragon based on the Hungarian Horntail?) There is so much possibility, also add broomsticks (if possible) which can fly to a certain height, and be controlled by SPACE and SHIFT?
I don't know, just an idea. Someone may have already suggested a similar idea, i don't know, but hey ho Someone should give it a try, because i for one would definitely download it.
