Reconciling this in our game has been tough - it seems like every time we use the spell the G.M. rules on it differently just because it's so damn confusing as written. Rather than go with the convenient "Time Stop for everyone but me" spell effect, I took a shot at re-wording the spell to be closer to what I thought was more like how it was designed to work. With this version the spell Temporal Maelstrom can even be used against the Time Stop spell caster, as per the description of Temporal Maelstrom. I'm interested to have this looked over and collect any feedback which anyone can provide:The effect will appear, to others, as if the character disappears for an instant and then suddenly reappears a few seconds later.
Range: Self.
Duration: Two melee attacks/actions.
Saving Throw: None.
P.P.E.: Twenty.
This invocation twists, warps and perverts time around the spell caster, enabling him to slip into a still moment of the near future. Once he arrives the caster has a few seconds (two melee attacks/actions) until time catches up with him. In the seconds before the normal flow of time resumes for everyone he may act, unseen and unknown to all those around him in this “frozen” moment of time. The magic is such that the character cannot physically hurt any living creature, but can move about the physical environment, open doors, grab an item, run, etc.
In game terms, the caster jumps forward in time by two melee attacks/actions. While he is gone the other characters play out those two actions as normal, keeping the same initiative order they had, as if the character who cast the spell had simply teleported away. In the third action since the spell was cast, on the caster’s initiative, the caster arrives and time for all the other characters is paused. The caster may now use two of his attacks/actions uninterrupted by anyone or anything else, subject to the restrictions noted earlier. Once those two actions have occurred then time resumes as per normal.
Note: From the standpoint of all the other characters, the caster disappears and then a few seconds later suddenly reappears in his new location, and at that same instant anything the caster manipulated or changed during the Time Slip suddenly shifts to the state or location the caster left it.
