It is important to read The Magistry's Sacred Magic main page.

"Arise," so says the Shadow Lord. You spoke a magical word to lift your comrades. Choose up to 6 willing creatures within your range, and they remove their prone condition. They also get temporary hit points equal to 1d4 + your spellcasting ability modifier. This spell does not affect fiends or celestials.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the temporary hit point gain increases by 1d4 for each slot level above 3rd.
