Spell damage reduction

Spell damage reduction is a special ability of several creatures. It's characteristic of Tower's Stone and Iron Golems as well as neutral Gold Golems and Diamond Golems. It reduces damage from spells by a specific percentage which depends on the creature type. However, it does not prevent spells from working as the manual claims.

Creatures with spell damage reduction:

•  Stone Golem - resists 50% of the damage from spells
•  Iron Golem - resists 75% of the damage from spells
•  Gold Golem - resists 85% of the damage from spells
•  Diamond Golem - resists 95% of the damage from spells
•  Firebird - originally fully immune to Fire Magic spells, in HotA  resists 50% of the damage from Fire spells
•  Steel Golem - resists 80% of the damage from spells
