Immune to Magic monsters have Magic Resist > 99%, and don't normally take any magic damage.
- While there is no way to remove immunity, Holy Bolt and Fist of the Heavens holy bolts ignore MR > 0% of undead.
- MR +20% is applied by the Mana Burn Unique bonus. If this results in MR > 99%, it is only applied if a monster has less than two immunities beforehand (in which case it either becomes Immune to Magic, or increasingly so).
- No Immune to Magic monster has Damage Resist > 50%, so even if DR +50% from Stone Skin results in a Unique becoming Immune to Physical this can always be removed with Decrepify or Amplify Damage.
