Defense Mastery: 30 base mana. No current weapon assignment.
Development source reviewed on 29 October 2026. In-game availability is unverified.
Ability information#
| Property | Value |
|---|---|
| Base mana | 30 |
| Availability | No current weapon assignment |
Requirements#
- Requires the equipped weapon’s assigned primary/secondary slot, normally 70/90 base weapon skill and (unless overridden below) 70/90 base Tactics. Use Best Weapon Skill can satisfy the weapon threshold with base Swords, Macing or Fencing.
- The inherited required secondary skill is Tactics base 50, in addition to the normal Tactics gate.
Effects#
- Source implementation: for three seconds, adds physical resistance equal to 50 + modifier and reduces the weapon damage-bonus input by 80 - modifier.
- modifier = truncate(30 × (max(Bushido,Ninjitsu) - 50)/70). Reapplying replaces the previous resistance modifier and timer.
Notes#
- No current weapon declares this ability. Physical resistance remains subject to the normal resistance cap. The damage penalty is applied to the damage-bonus input, not a direct final-damage multiplier.
- Base mana is reduced by the shared ability skill-total discount and Lower Mana Cost rules; a second paid ability within the three-second cooldown costs double.
