Temporary Spell Immunity: Passively grants Spell Immunity. This effect can be extended.
Spell Immunity: Any cast Spells won't affect you. (This includes non-targeted Spells.) This effect also protects you when you pass through the Cursed Gate in the Archaeology Dig.
If you are targeted by any Spell while you have Spell Immunity, the Spell will do nothing at all to any player.
If you are the caster of On Love's Wings or Life Link or Dark Sacrifice while you have Spell Immunity, the Spell will do nothing at all to any player.
Steal Item, Spellsteal, Burden, and Runes Of Guidance only "affect" the target as far as Spell Immunity is concerned, not the caster. As such, if the caster has Spell Immunity, the Spell effects can still function normally.
