Separate grade, casting speed, PvP effects and the exact SA skill level.
Compare the exact weapon’s base attack, enchant level and Special Ability separately. Do not apply a flat damage multiplier from its grade label alone. Sword of Miracles [Acumen] advertises +15% casting speed and an additional PvP effect: casting speed is not spell damage.
Arcana Mace [Acumen] likewise lists +15% casting speed and increased PvP damage. Tallum Blade [Haste] instead lists about +6% attack speed plus a PvP damage effect. These are the enhanced variants, not a promise of identical bonuses on every A/S weapon.
Homunkulus’s Sword [Acumen] and Sword of Valhalla [Acumen] list the +15% casting-speed effect without the additional PvP line shown on those A/S examples. This comparison covers these exact C/B variants; missing tooltip text is not a complete audit of every lower-grade weapon.
Special Ability: PvP Damage, skill 3552 level 1, records +5% for normal physical attacks and +5% for magical-skill damage in PvP. Its record does not establish a physical-skill modifier. These are effect-level values, not proof that every weapon grants this skill.
Special Ability: Acumen, skill 3047 level 2, records +5% PvP modifiers for normal physical attacks, magical skills and physical skills. Level 1 lists only casting speed. Therefore, saying that physical-skill modifiers are absent from all Interlude SA records would be wrong. Match the weapon to its exact SA and level before applying a modifier.
