Yeah, cure wounds has changed schools a few times LOL!
It is do to the nebulous and unexplained nature of it and many spells.
If it is emitting rejuvenating positive healing energy, it's Evocations.
It it is summoning the rejuvenating positive healing energy from a god or other plane, it is Conjuration.
If it is emitting rejuvenating anti-death energy, it is Necromancy.
If it is creating a positive shield around your last 1 HP, it is Abjuration.
If it is knitting closed minor cuts and bruises, it is Transmutation.
If it is giving you a glimpse of a future fatal event, it is Divination.
etc. it can any school.
Cure Wounds and Healing Word both being Evocations means they are created jolts of healing divine or primal energy.
But why is every jolt of created energy Evocations except necrotic, psychic, and sometimes acid and poison.
It should be consistent
- acid- Conjuration (acid is not energy)
- cold- Evocation (unless conjured)
- fire- Evocation (unless conjured)
- force- Evocations (unless conjured)
- lightning- Evocation (unless conjured)
- necrotic- Necromancy
- poison- Conjuration (poison is not energy)
- psychic- Enchantment
- radiant- Evocation (unless conjured)
- thunder- Transmutation (it is giving someone a vibrating state without heat)
Spells that have variable damage should almost all be Conjurations from other planes or Transmutation of existing energy or matter.
