Sync's Moment of Compunction/Conviction

Seeing the strands of time around you, you manipulate them in an effort to turn the tide of battle.  You are able to give an initiate boost or penalty to any creature that has an initiative turn.  You can target a single ally or hostile creature and choose their new initiative placement only after they have taken their first turn in combat.  Hostile targets must succeed on a wisdom saving throw or be affected by the spell.

The affected creature's new initiative turn order continues for the remainder of combat.  A target can only act once per round.  If you increase a targets initiative ahead of your own and they have not acted in this round yet, they will act immediately following your turn in the current round and ahead of you in subsequent rounds.  If you decrease a creature’s initiative that has already acted this round they are not able to act again in the same round, their new initiative will occur in the next round.

At Higher Levels.  When you cast this spell using a spell slot of 3 or higher, you may target another creature for every slot above 2.
