Blaze's Pride Flare

Choose a willing creature that you can see within range. Until the spell ends, the target is immune to being frightened or petrified, gains 20 temporary HP, has advantage on strength-saving throws, and cannot retreat from any combatant. 

When the spell ends, the target becomes frightened of any enemy it attacked AND failed to kill, for an entire round.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the target gains 5 additional temporary hit points for each slot level above 3rd.
