Everything

Up until Rank 4, the Entropy Sphere does not inflict damage. It can, however, lead to hazardous coincidences: a speeding car, a weakened floorboard, a falling candle, and so forth. Again, the circumstances must be present in order for them to be manipulated this way – a falling candle won’t fall and start a fire if there hadn’t been a candle there in the first place.

Once again, the nature of the hazard and the damage it inflicts remain under the control of the Storyteller unless the player wants to invoke vulgar magick. Leading an enemy into speeding traffic so that he might get hit by a car involves the powers of coincidence, but yanking a car out of its way so that this particular car WILL hit the enemy is vulgar magick. And again, a very likely hazard (like a speeding car on a street) requires fewer successes than a very unlikely one (a lump of frozen poop falling from an airplane).

For the amounts of damage caused by various dangerous things, see the Environmental Hazards section of Mage 20,
