Spell Details
Player Guide
Cast Aid before combat or during lulls to grant three allies +5 HP as both a current and maximum increase, effectively giving them free hit points that scale with their health pools. This spell is particularly valuable for squishy characters (wizards, rogues, clerics) and works best when cast during short rests or before anticipated fights since it lasts 8 hours. The maximum HP increase also benefits abilities that scale with HP, such as Barbarian rage damage or monk ki point calculations. Upcast this spell at higher levels—each spell slot above 2nd adds +5 HP per target, making it scalable throughout the campaign.

DM Tips
Clarify whether Aid's maximum HP increase persists if the spell ends mid-combat—typically current HP cannot exceed the new maximum. Remember that upcasting Aid is extremely efficient; a 3rd-level slot grants +10 HP per target, making it a competitive action even at higher levels.
