Swordsmanship

Swordsmanship is the largest weapon class in Britannia by roster, the gateway skill for the iconic Sampire build, and the only weapon skill that pairs with Lumberjacking for an axe-only damage bonus. The skill governs hit chance with every blade, axe, and polearm in the swordsman category — base damage is paid by Strength and Tactics, swing speed by Stamina and Swing Speed Increase, and the swordsman's accuracy by this skill alone.

Mechanics

Swordsmanship is one of the seven combat-defense skills (alongside Mace Fighting, Fencing, Archery, Throwing, Wrestling, and Parrying). Each combat round it is rolled against the target's defensive skill to determine whether the swing connects:

hit_chance = (attacker_skill + 50) / (defender_skill + 50) / 2

before Hit Chance Increase and Defense Chance Increase modifiers. Higher Swordsmanship raises the hit floor for any defensive skill the target carries; against a 120-skill defender, an attacker needs 100 Swordsmanship to land roughly 50% of swings before HCI/DCI math.

The skill counts toward the special-move requirement (70 for primary, 90 for secondary) and toward the 200/300 combined-skill thresholds for −5/−10 mana on specials. Combined with Tactics and Anatomy at GM, every swordsman naturally clears the −5 tier; adding Bushido or another combat skill at GM clears −10.

The Lumberjacking axe bonus

Of the swordsman's two-handed roster, the axes carry an additional Damage Increase bonus tied to Lumberjacking — exclusive to Swordsmanship and unmatched in any other weapon class:

axe_damage_bonus_pct = Lumberjacking / 5 + (10 if Lumberjacking >= 100)

GM Lumberjacking on an axe-swinging swordsman adds a flat +30% damage on top of Tactics, Anatomy, and item Damage Increase. Despite the cost (100 skill points for 30%), the bonus is the entire reason classic Sampire builds use a Double Axe or Bardiche — once the points are committed for resource gathering anyway, the axe bonus is free.

The bonus applies only to axe-class weapons (Axe, Battle Axe, Bardiche, Double Axe, Executioner's Axe, Hatchet, Large Battle Axe, Ornate Axe, Pickaxe, Two-Handed Axe). It does not apply to swords, knives, or katanas — even the Sampire Swordsman who pivots to a Soul Seeker for a fight loses the Lumberjacking bonus for that swing.

Skill Mastery — The Way of the Sword

Reaching 90 real Swordsmanship and reading any-tier Mastery Primer activates the Onslaught / Focused Eye mastery line. Title: The Champion of the Sword.

Onslaught is the boss-burst mastery — used at the start of an extended fight to accelerate damage. Focused Eye is the PvP mastery, opening a brief window where the swordsman lands every swing through DCI defense.

Poisoning interaction

Pre-Poison-Mastery (and the Injected Strike spell), the only Swordsmanship weapons that could carry classical applied poison were the Butcher Knife and Cleaver — both Tinker-crafted. Every other sword, axe, or polearm rejected the Poisoning skill's apply step. Modern UO removes that restriction in two ways: Poison Mastery can poison any weapon for the mastery duration, and the Injected Strike Mystic spell delivers a poisoned hit through any weapon. Pre-existing applied poison still requires the Tinker pair.

Training

Power Scrolls are the bottleneck; the 120 Swordsmanship scroll is one of the most expensive in the game on most shards because of the Sampire build's broad popularity.

Build context

• Sampire — 120 Swordsmanship, 120 Tactics, 120 Anatomy, 100 Necromancy, 100 Chivalry, 100 Bushido, GM Lumberjacking. Vampire form leech + Bushido Perfection + Lumberjacking-axe stack is the canonical PvM bossing template; runs Soul Seeker, Bone Harvester (for Mortal), or Double Axe (for Whirlwind).
• Pure Swordsman — 120 Swords, 120 Tactics, 120 Anatomy, 120 Parrying, 120 Bushido, ~100 Healing/Chivalry. No Necromancy; relies on shield-and-katana defense.
• Mage Weapon Sword — Soul Seeker or Magery-bonus runic blade with the Mage Weapon −20/−25 property; pairs Magery casting with sword swings via the Onslaught mastery for boss damage. Uses 80 Swords + jewelry rather than a real 120 build.
• Sword + Throwing Gargoyle — Gargoyles cannot use bows but can use most swords; pairs a Soul Seeker melee profile with a Boomerang or Soul Glaive for ranged opening.

Strategy notes

• Halberd vs. Bardiche. The Halberd has higher base damage (18–21 vs 17–20) and Whirlwind primary, but slower swing (4s vs 3.75s) and no Dismount. Bardiche is the PvP pick for Dismount-Para; Halberd is the PvM pick for AoE.
• Double Axe Whirlwind. Best AoE-per-second axe in the swordsman roster; pairs with Bushido for the Whirlwind damage formula scaled by adjacent enemies.
• Bone Harvester is the Mortal Strike weapon. Faster than the Crescent Blade with a more useful primary (Para over Double).
• Soul Seeker (uncraftable, drops from various peerless and Stygian Abyss boss tables) is the Sampire damage standard at high levels — extremely high base damage, Bushido-class Whirlwind, and built-in property bonuses.
• No-Dachi is the only swordsman weapon with Riding Swipe — useful for dismount-and-trample PvP openers.
