Physical damage is one of the five Damage Types. It is the most common and the only one reduced by Armour, rather than by a Resistance.

Most physical damage comes from Weapon Attacks, but some Spells and other skills deal physical damage as well. Physical damage over time can be inflicted with Bleeding.

A Projectile is a moving Attack or Spell that usually impacts with targets when it hits them.

When a group of multiple Projectiles is fired from the same source at the same time, only one Projectile in the group can hit each target unless otherwise specified.

Critical Hits deal +100% extra damage (i.e. twice as much damage) by default. Critical Damage Bonuses can further modify this value.

Attacks usually use your weapon's base Critical Hit Chance, while Spells and some other skills have their base Critical Hit Chance listed on the skill.

Most modifiers to Critical Hit Chance are percentage based. For example, gaining 100% increased Critical Hit Chance on a base Critical Hit Chance of 7% would result in a final Critical Hit Chance of 14%.

Attacks are skills that directly use your equipped weapon to damage enemies. Spells are not Attacks.

The base damage, attack speed and critical hit chance of an attack are determined using your weapon's stats unless a skill says otherwise.

Attacks do not necessarily deal Physical damage — they can deal any damage type.

Sceptres are One-Handed weapons that require Strength and Intelligence to equip. Sceptres can be equipped in your main hand or off hand, but you cannot Dual Wield two Sceptres.

Sceptres cannot be used to Attack and do not grant bonuses to Spellcasting. Instead, they grant additional Spirit and can provide bonuses to your Allies.

Wands are One-Handed Spellcasting weapons that require Intelligence to equip.

Wands cannot be Dual Wielded and cannot be used to Attack directly. However, they grant inbuilt Spells based on the wand type and powerful bonuses to spells.

Daggers are One-Handed Melee weapons that require Dexterity and Intelligence to equip.

Dagger Attacks are commonly related to ambushing or debilitating enemies. Some blade-related Spells also require a Dagger.

Staves are Two-Handed Spellcasting weapons that require Intelligence to equip.
Staves cannot be used to Attack. However, they grant inbuilt Spells based on the staff type and powerful bonuses to spells.

Foci are armour items that are equipped in your off hand and require Intelligence to equip.

Foci can grant significant amounts of Energy Shield and powerful bonuses to your Spells.

Thorns damage is a kind of Hit Damage you can deal. Thorns damage is not Attack damage or Spell damage and is not affected by modifiers specific to those.

If you have Thorns damage, you inherently Retaliate against Melee Attack Hits, dealing your Thorns damage to the enemy that Hit you.

Some skills and other effects may also deal your thorns damage to enemies at other times.

Affects the speed at which all Skills are used. Increases and reductions to Skill Speed stack additively with increases and reductions to Attack Speed, Cast Speed, Warcry Speed, and similar stats.

Unleash is an effect that allows Spells to accumulate Seals that allows the Spell to reoccur when being cast. There is a limit of 2 Seals per Spell.

Archons are a type of Buff that augment your Elemental prowess with Spells. There are Archon Buffs related to each Element: Flame Archon, Ice Archon, and Lightning Archon.

By default each Archon Buff lasts 10 seconds, but will be removed early if you use any non-instant Attack.

You cannot gain any Archon Buff while you already have one, or during a recovery period after you lose one, which lasts 20 seconds by default.
