True Immunity

You enhance the immune system of a creature within range. For the duration, the target gains the following benefits:

• It is immune to poison and necrotic damage.
• It is immune to disease.
• It is immune to the following conditions: blinded, charmed, deafened, paralyzed, petrified, and poisoned.
• Its ability scores cannot be lowered, and its hit point maximum cannot be reduced.

When the spell is cast, if the creature has a disease, a condition it’s now immune to, or an effect lowering its ability scores or hit point maximum, those effects are suppressed for the duration.
