I've played through the game a few times checking every door, locker, body, etc. in the school and I'm always missing 4 pieces of equipment. I know its not the: - Dodge Ball - Mace of Restoration - Necromancer Set (Hood/Robes/Gloves) - Basketball Anyone know what 4 pieces I'm missing and where they might be? Really trying to get the achievement for collecting everything. Thanks in advance!
