Bolstering Blade

As part of the casting of this spell, you may make one melee weapon attack. if the attack hits, it deals an extra 2d6 damage of a type based on your diety/patron, you gain temporary HP equal to the extra damage dealt, and all temporary hp gained by this spell is considered to be gained from the same source, and is capable of stacking with itself, but not with other abilities that grant temporary HP. if another ability would attempt to grant temporary hp that is higher than the current total granted by the spell,  the spell ends. you can also end this spell yourself (no action).

The temporary HP gained from this spell cannot exceed an amount equal to your current max HP*2 (ex: a player with Max 10 hp using this spell cannot gain more than 20 temporary hp from it.) any granted beyond this amount during the spell's duration is lost.

if you cast this spell using a higher level spell slot, the extra damage increases by 1d6 for each level above 1st level.
