Baldur’s Gate 3 Equipment: Weapon Proficiency and Armour Class
On this page
Read the character and the item together
A weapon is useful when its requirements and properties fit the person holding it. Check proficiency, the ability used for attacks, and the actions the weapon provides before comparing the largest damage number.
Weapon proficiency contributes the proficiency bonus to applicable attack rolls. It is not simply extra damage on every hit. Finesse weapons use the higher of Strength or Dexterity for their attack and damage rolls, which makes them worth inspecting for a Dexterity-focused character.
| Property | What to check before equipping |
|---|---|
| Finesse | Whether Strength or Dexterity is higher on this character. |
| Light | Whether both weapons meet the normal requirements for an off-hand setup. |
| Two-handed | Whether losing access to a shield fits your plan. |
| Versatile | Whether you want the weapon used in one hand or two. |
| Range | Whether your intended target is within effective reach. |
Armour Class helps attacks miss
Armour Class is the threshold an attack roll must meet. A higher value makes ordinary attacks harder to land; it does not mean every incoming hit is reduced by that number.
Compare the character’s resulting AC after equipping an item. Also read its special effects and any restrictions. A piece that improves a specific spell or class feature can be useful even when it does not have the highest rarity or the most impressive-looking model.
Keep saving throws separate from AC. If a spell forces a saving throw, improving your armour alone may not solve the problem that defeated you.
For a specific Act One crafting choice, the Adamantine Forge guide covers all six moulds, the limited ore supply, and the proficiency checks to make before choosing armour or a shield.
Fix proficiency problems before fighting
Armour has proficiency categories, and shields have their own proficiency requirement. Some helmets, gloves and boots also count as armour, so check more than the chest slot.
Wearing armour without proficiency prevents spellcasting and imposes serious disadvantages on rolls. If a caster suddenly cannot use spells after changing equipment, inspect every newly equipped piece before assuming the spellbook is broken.
This check matters after a respec. The old loadout may no longer suit the new class. Swap incompatible pieces while still at camp, then verify the character can use their intended actions.
Compare a complete turn
Do not evaluate a weapon only by its strongest possible hit. Think about its chance to connect, the position required to use it, and what the character can do if the enemy stays out of reach.
Keep a suitable ranged option on characters who mainly fight in melee, and place frequently used consumables where you can find them. If a new setup still struggles, use the combat log guidance to identify whether accuracy, resistance or a saving throw is responsible.
