When Ilyykur's mantle is called into being, the caster is surrounded by a luminous aura that completely covers him, conforming to the contours of his body. The mantle does not affect any physical or magical abilities of the caster, but does affect spells that are cast against the wearer. These effects are:
- +3 on all saving throws vs. enchantment/charm spells that allow a saving throw. The mantle does not give a saving throw against spells that do not normally allow one;
- +1 on all other saving throws vs. spell, again provided that one is allowed under the spell description;
- All damage from electrical attacks, including shocking grasp and lightning bolt, is halved (saving throws can negate or halve the damage again).
The mantle protects only the caster and the caster's familiar, provided that the creature is relatively small (size S) and remains in contact with the caster.
The material component of this spell is a natural (not cut or finished) gem.
Notes: Rare or very rare spell from the Forgotten Realms setting. Known to be in the Tome of the Covenant.
