• ATK: Attack
• CDMG: Critical Damage
• PEN: Penetration
• DEF: Defense
• DMG AMP: Damage Amplification (PDMG/MDMG increase, PWeakness/MWeakness)
• ATK SPD: Attack Speed
• UW: Unique Weapon
• UT: Unique Treasure
• T5D: Transcendence 5 Dark Perk
• S1/2/3/4: Skill 1/2/3/4

Takes into account all ATK/CDMG/Flat ATK buffs you get from gears, skills, enchants, runes, perks, and artifacts, then calculates the optimum amount of ATK/CDMG lines you should aim for in your gears. It aims to balance between your ATK and CDMG in order to maximise damage per hit. (ie. ATK SPD does not apply)

Enemies are taken to be at 0 DEF (ie. test dummy), and assumes all buffs are at its maximum stacks and every buff stacks together. All attacks are crits.

The formulae are:
Damage per AUTO ATTACK hit = [(statMenuATK x (100% + ATK%buff)) + flatATK] x (200% + statMenuCDMG + CDMG%buff) x DMGboost% x heroScaling

Skill Damage per hit = [ skillBase + ((statMenuATK) x ATK%buff + flatATK) x skillATKmultiplier ] x totalCDMG x (skillBooks + damageBoost%)

This formula is still applicable towards enemies with non-zero DEF as the damage reduction by DEF is calculated after the above formula.

1. Select your hero.
2. Fill in your hero's gear setup, and desired number of ATK/CDMG lines.
3. Select the skill/perk buffs you want to take into account of. The stats for each skill are based on lvl90, maxed book effects stats, and are simplified to ATK, CDMG, Flat ATK. Damage increase effects are separated into another section. If you are unsure about the skill mechanics please refer to the relevant Mask-of-Goblin page.
4. Fill in the artifact stats.
5. Fill in any other additional stats (guild buffs, self/skill dmg boost, ignored stats in skill selection) in the additional stats section. Refer to this list.
6. For skill damage, fill in the skill base value at lvl90, skill ATK multiplier and skill books damage boost.
7. Click calculate and view your results.
8. Fill in the DEF and PEN value if you wish to see the effects of PEN.
9. Repeat for any other hero you want.

This calculator does not give you the values for the following buffs/effects:

• Guild buffs
• Self/skill-only damage buff % (Increase damage by ..., boss damage etc. that only affect self/skill)
• Skill-only ATK/CDMG/Flat ATK buff
• Additional ATK boost based on other character stats (eg. Mediana S3)
• Additional ATK boost based on other stats (PDEF, Mana/sec etc.)
• Additional attack per hit (Kasel UW effect, Phillop HP% damage etc.)

However, you can workaround these by adding them at the additional stats section: (you will need to calculate the amount to be added by yourself)

Refer to this list for the special cases heroes.
