Temporal Push

A half-formed slipgate hurls the target forward in time by up to 1 round + 1 round/level, chosen before casting. The victim experiences no gap; the world simply lurches. An occupied return space displaces them slightly. Both caster and target make Wisdom checks: each point by which the caster succeeds adds +1, to a maximum of +4, to the target's roll. If the caster fails and the target succeeds, the CASTER is pushed instead. DM note (p. 65): a pushed-forward caster looks as though he fled, and a spellcraft-proficient wizard who knows the spell can identify what happened.
