Rise of Madness
Soft Cover: When firing at a target through other individuals, you may choose to either take the -4 penalty to hit, or you may choose to take the alternative:
If you miss the AC of your target, each individual (in order of proximity) in the flight path of your missile must make a REF save = 10+(your BAB). If they fail, the missile stops at them, and if it beats their flat-footed AC (or their touch, flat-footed for ranged touch attacks) the missile hits them. Otherwise it plinks off of them.
Melee touch spells: You do not provoke AOO’s for using a stored melee touch spell, and when casting one defensively you gain a bonus on the concentration check equal to the spell level.
