Celestial Favor

with a magnanimous gesture and a quickly uttered blessing, a celestial warlock may grace up to three creatures of their choice within range with divine favor. Whenever a chosen ally makes an attack roll or a saving throw before the spell ends, they can roll a d4 and add the result to attack or saving throw rolls.

Note: When you cast this spell using a spell slot of second level or higher, you can target one additional ally for each slot level above 1st.
