your healing spells are more effective. Whenever you use a spell of 1st level or higher to restore hit points to a creature, the creature regains additional hit points equal to 2 + the spell’s level.
What happens when I cast a level 1 spell using a level 2 spell slot?
Literal reading would suggest that the spell slot is irrelevant only the inherent level of the spell but I have seen statements to the contrary.
It’s not a huge difference. But I’d still like to know.
My DM does it based on the spell slot used.
When a spellcaster casts a spell using a slot that is of a higher level than the spell, the spell assumes the higher level for that casting. For instance, if Umara casts magic missile using one of her 2nd-level slots, that magic missile is 2nd level.

Higher level spell slot means higher level spell.
Thanks!
