*Giving a character the ankheg sprite lets them burrow just like an ankheg does. They will stay underground as long as they aren't attacking someone. They can actually cast spells while burrowing without coming up.
*The effect that let's the Wizard Eye clear the fog of war will do the same thing if put on a neutral or enemy creature. You'll be able to see what that creature sees, even if there are no allies nearby. You could make a divination spell that lets the wizard see through the eyes of the target.
*If you make an effect that modifies damage resistance so that it sets the resistance to a percent, and you set the percent to a negative number, you can invert the target's resistances. For example, if you give someone who has 50% fire resistance an effect that multiplies its fire resistance by -100%, that creature will become 50% weak to fire. You could make a spell that inverts all the target's damage resistances in this way.
*If you give a shaman protection from opcode 363, they will be able to move while dancing.
*You can do some cool things with opcode 366. When a creature with the effect moves, the effect casts a spell on the creature and then the effect goes away. However, you can make it so that one of the effects of the spell is another opcode 366 effect, so you can cast the spell over and over again while moving. I gave my character such an effect. When she moves, she automatically casts a spell which gives her the same ability as well as a wing buffet effect, pushing her away from the target, which is where she was at the moment the spell was cast. She can't move without skidding all over Candlekeep. I just figured out how to make ice physics in Baldur's Gate!
