Damage calculator

The calculator shows the damage of every ability on a weapon at the item power (IP) you choose. It uses the weapon’s own numbers from the game files.

1. Search for a weapon, or pick one of the popular weapons.
2. Move the IP slider to your item power. Or switch to Tier / Enchant / Quality and build the IP from your item.
3. Pick an activity to apply its IP cap, for example 1v1 Arena or CD (Hunter) for a Corrupted Dungeon.
4. Read the damage of each ability, and the table of damage at each IP step.

Albion Online scales ability damage with item power like this:

damage = base damage × (ability power ÷ 100) × f ^ (IP ÷ 100)

Base damage is the ability’s value in the game’s spell data. Ability power is a stat of the weapon. The factor f is 1.0825 for one-handed weapons and 1.0918 for two-handed weapons. So each 100 IP adds 8.25% damage to a one-handed weapon and 9.18% to a two-handed weapon. The gain compounds: 200 IP more is not twice the gain of 100 IP, it is a little more.

Item power comes from the tier, the enchantment and the quality:

IP = base IP + 100 × enchantment level + quality bonus

Some activities cap item power. With a soft cap, only part of the IP above the cap counts. With a hard cap, none of it counts.

effective IP = cap + (IP − cap) × share that counts

Heroic Strike on the Adept's Broadsword has a base damage of 77.81. The weapon has 138 ability power and is one-handed, so f = 1.0825. At 700 IP:

77.81 × 1.38 × 1.0825 ^ 7 = 187.0 damage

Take the 1,300 IP version into Arena (1v1). The cap is 900 and 20% of the IP above it counts. The effective IP is 980, so Heroic Strike deals 233.5 damage instead of 300.9.
