Information-gathering abilities, or means of understanding others' motivations, intentions, and desires. This is a potentially very powerful category of abilities, and thus requires careful power-balancing. Many people want to be able to affect their luck, or the luck of others, in a positive or negative direction. You'll need to carefully power-balance luck abilities simply because of their potential breadth. This is one area where you'll want to keep abilities narrow and specific.
Protection is one of the most powerful desires.
If you steal something from a bank without ever entering the bank, after all, you never show up on their cameras, you leave no trail of evidence, and their guards can't shoot at you. As we mentioned last issue, if you really want to play with powerful abilities like these but don't want them to unbalance your game, you still have a few options. Make the abilities require heavy preparation, rare items, or other limitations. Alternatively, make the ability, item, or ritual dangerous, or give it nasty side-effects. They could control the weather, cause a trail of light to spell out words in the air, change the color of paint on a wall, make a room smell like daffodils, or cause an explosion of light in front of someone that blinds them temporarily.
