Arms Lore

このコンテンツはまだ日本語訳がありません。

Arms Lore is the appraisal skill for arms and armor: it reads a weapon or armor piece’s condition and quality. On this shard it also gives a crafter a small bonus to the exceptional weapons and armor they make. The behaviour below is verified against ServUO source.

What it does

Two distinct things:

Inspect gear — Use the skill and target a weapon or armor piece to learn its durability (how worn it is) and a description of its damage (weapons) or armor rating (armor). A failed check just says you’re “not certain” — higher skill reads more reliably. This is its active function (Scripts/Skills/ArmsLore.cs).
Improve your exceptional crafts — see the next section.

How to use it

Activate the skill and target a weapon or armor piece — in your pack, equipped, or on a vendor — to read its details. The crafting bonus is automatic: it applies when you craft, and crafting also trains Arms Lore passively (each exceptional craft rolls a gain check).

Does Arms Lore affect weapon-making?

Yes — but not the way it’s often assumed. Reading the source settles a common misconception:

It does not raise your success or exceptional chance. Arms Lore is not referenced anywhere in the crafting engine (Scripts/Services/Craft/). Your chance to succeed and to produce an exceptional item comes from your crafting skill, Strength/Dex, and tools — Arms Lore plays no part in whether a craft turns out exceptional.
It does sweeten an item that’s already exceptional (on this ML/EJ shard). When you craft an exceptional piece, your Arms Lore adds bonus properties on top, scaled by ArmsLore / 20:
- Weapons (BaseWeapon.OnCraft): Damage Increase += ArmsLore / 20. At GM (100) Arms Lore that’s +5% DI baked in — on top of the +35% DI an exceptional weapon already grants.
- Armor (BaseArmor.DistributeExceptionalBonuses): ArmsLore / 20 extra resist points, each randomly assigned to Physical/Fire/Cold/Poison/Energy. At GM that’s +5 total resist spread across the five types, on top of the normal exceptional bonus.
- Clothing gets a similar bonus (capped at +4).
- (On a Siege-ruleset shard the divisor is 12.5 instead of 20, i.e. +8 at GM; this shard uses the standard 20.)

So a smith or tailor who maxes Arms Lore turns out better exceptional gear — more damage on weapons, more resist on armor — even though Arms Lore never changes how often they hit exceptional. For a crafter, GM Arms Lore is a genuine (if modest) upgrade to every exceptional weapon and suit they make. See Crafting and Blacksmithy / Tailoring.

How to train it

Quick start: an NPC trainer (a Samurai or weapon/armor vendor with the skill) teaches up to one-third of its own skill, capped at 42.0 (Scripts/Mobiles/Normal/BaseCreature.cs, CheckTeach: baseToSet = ourSkill.BaseFixedPoint / 3) — buy to ~30–42 first.

Arms Lore is an active “read” skill — Use it on a weapon or armor piece and it rolls a gain check each time:

Low/mid skill — keep a stack of crafted daggers or looted armor and examine them over and over; it is one of the faster read-skills to raise.
High skill — keep examining gear, or let it ride along while you craft. GGS guarantees the slow late points if you keep reading.

Gain notes	training Arms Lore raises Int (primary), or Str (secondary) — see Stat gain

Arms Lore’s primary stat is Intelligence — it is an appraisal/knowledge skill, not a combat one.

Blacksmithy / Tailoring — supports the quality of crafted gear.
Item Identification — the broader appraisal skill for non-weapon items.
Weapon skills (Swordsmanship and the rest) — fighters who want to read their gear at a glance.
