Healing with spells
The glyph from Cawwot (spell) counts as being placed by the caster, so it is based on the caster's statistics and not the summon's.
Healing with Summons
The effectiveness of a summon's healing spells are increased by 1% for each of the character's levels. Summons' heals are not affected by the intelligence of the summoner.
Note: The Barrel summoned by Drunkenness only heals while being carried.
Healing with Weapons
See Healing weapons for a list.
