Caddelyn's Catastrophe

This spell allows the caster to affect up to four creatures if desired, all of whom must be visible to the caster during casting. If four creatures are attacked, their saving throws (vs. spell) are normal; if three are attacked, all save at -1; if two are attacked, they save at -2; and if only one is attacked, the save is at -3. Creatures who make their save are slowed (cf. Slow spell, PLAYERS HANDBOOK) for the duration of the spell; creatures who fail immediately drop all held objects, trip or stumble if running or charging, fall if balanced on a ledge or climbing, and have any spellcasting ruined. Any missile attack launched by an affected creature will miss (the spell takes effect instantly), and any physical attack will be at -2 to hit. If it was a weapon attack, the weapon is dropped and the attack becomes a bare fists attack. Dropped items may well suffer damage (saving throws to avoid). Target creatures must be within range, but need not be together; they may be on opposite sides of the caster. Affected creatures who move out of the spell range are freed of the spell, but they will suffer its effects again (no saving throw) if they re-enter spell range before the spell expires. (Magic may be cast normally from outside the spell range into it.)
