Inscription and spell damage

From UO:PvE Wiki

Inscription contributes up to 10 percentage points to supported spell-damage calculations, reaching its maximum at 100.0.

Development source reviewed on 29 October 2026. In-game availability is unverified.

The bonus curve#

Effective Inscription above 50.0 adds damage bonus at 0.2 percentage points per skill point. The bonus caps at 10 percentage points at 100.0; training above 100 does not increase this particular bonus.

Where it applies#

The standard spell-damage calculation includes Inscription alongside Intelligence and equipment Spell Damage Increase. Separate supported paths include Mind Blast, Poison Strike, Wither, Pain Spike, Strangle, Holy Light and weapon spell-damage procs.

  • This is a damage benefit; do not treat it as a blanket healing bonus.
  • In the standard damage calculation, the Inscription contribution is additive with other damage-bonus terms. A 10-point contribution does not always mean the final hit is 10% larger.
  • The equipment Spell Damage Increase cap against another player is a separate 15% limit; it does not replace the Inscription formula.
