Spell Damage Increase (SDI) is an item property that, surprisingly, increases the damage of most magical attacks that are cast. While this property is capped at 15% for PvP, the cap further increases from 15% to 30% for templates having no more than 30 modified skill points in another main skill like Magery, Necromancy, Mysticism, Focus, Ninjitsu, Bushido, Animal Taming, Musicianship, Chivalry and Spellweaving. For PvE there is no cap on spell damage, so pack it on.

There is no formula needed for Spell Damage Increase because it is a true conversion, a 10% increase means your spell damage is increased 10% and so on. The intensity range of the Spell Damage Increase item property is 1% to 18% for found rings and bracelets. The apparent maximum is 30% for special items (e.g., War of Shadows Invasion Spellbooks).


As with most code over time, Spell Damage Increase is not as straight-forward as it seems. It does affect Poison Strike and Wither, but it does not affect Pain Spike or Holy Light. It works with Word of Death, as the spell is not dependent on a secondary ability check, e.g. like Pain Spike, which involves Spirit Speak, or Holy Light, which involves Karma.

Calculating Spell Damage

  • A character's skill level of evaluating intelligence is the first thing that comes into play in calculating the base spell damage. The formula for how much spell damage your getting from your Evaluating Intelligence is this: ((evaluating intelligence * 3) / 100) + 1
  • The next factor involved in spell damage is intelligence. The formula for this is 1% spell damage increase for every 10 points of intelligence, or (intelligence / 10) and drop the decimals.
  • The next factor is the inscription Skill bonus. This bonus only takes effect when a character has achieved the level of Grandmaster or higher in Inscription. This is a 10% increase in the base damage for Magery Spells.
  • Spellweaving spells Arcane Empowerment and Reaper Form increase spell damage.
  • A bards Inspire & Invigorate buffs boost the spell damage too.
  • Getting the Guild of Arcane Arts trade deal city buff increases the SDI value by 5
  • Factor in any SDI imparted from items.
  • Remember the well timed usage of an Spell Focusing Sash
  • Last but not least, the Summer Dragonfish Pie gives a straight +5 spell damage
