About this calculator
The figures added up here are the Level 5 values from the arcana list, transcribed on 2026-09-24.
The bracketed figure under a defense value is the damage reduction it buys: defense ÷ (defense + 600). All 232 defense readings measured across 116 heroes match that formula.
The base stats are the level 1 values; levels and items stack on top during a match. Arcana values never grow, so their effect weighs heaviest in the early game.
