Tiny Alacrity

Upon facing immediate danger, you draw a spell sigil in the air, visualize possible timelines, and choose one in which the selected creature(s) reaction was quicker.

Before a battle starts, if you're not surprised, you can spend a reaction to cast this spell. Choose a willing creature you can see within 30ft (you can also target yourself), and the target can add its proficiency bonus on top of its initiative roll. This must be done before the first round of combat.

At higher levels. When you cast this spell using a spell slot of 2nd level or higher, you can target one additional creature for each slot level above 1st.
