Deadlock build calculator

Every number in this panel is computed by this site from the game's own files: the hero's base stats, per-level gains, gun and investment tables, and each owned item's unconditional stat bonuses. Bonuses that apply only in a condition (close range, vs. NPCs, while an ability is active) are never added. The formulas follow the Deadlock wiki's pages on health, weapon damage, fire rate, damage resistance and spirit power.

• Max health = ceil((base health + (level - 1) x health per level) x (1 + (vitality investment percent + base health percents) / 100) + flat bonus health).
• Bullet damage = (base bullet damage + (level - 1) x bullet damage per level) x (1 + weapon damage percent / 100). The weapon investment percent and every item's weapon damage percent are summed into one multiplier. The files do not say how the engine stacks them; the in-game shop panel shows one summed Weapon Damage figure, and that is what this mirrors.
• Rounds per second = (1 / cycle time) x (1 + fire rate percent / 100). Weapon DPS = bullet damage x bullets per shot x rounds per second, with no reload, falloff, crits or headshots.
• Clip size = floor(base clip x (1 + clip size percent / 100)) + flat clip size.
• Bullet and spirit resist = 1 - (1 - r1 / 100) x (1 - r2 / 100) x ... over every source, the hero's per-level resist included.
• Spirit power = ((level - 1) x spirit power per level + spirit investment + flat item spirit power) x (1 + spirit power percents / 100).
• Move speed, sprint speed, stamina and health regen are the base plus the item bonuses; lifesteal, melee damage and cooldown reduction are plain sums. Stacked move speed's diminishing curve is not modelled.
• Other bonuses are listed as the plain sum of the items that grant them, with no formula claimed, including max health percent penalties.
• Investment: the souls in each category are the full cost of the items you own there (an upgrade's cost includes its component once); the bonus is the highest threshold reached, from the hero's own table.
• A hero holds at most 12 items (9 base slots plus 3 extra), engine behaviour cited to the 2025-11-21 patch note. Selling returns half the purchase price, the client's own rule.
