Calculation model & limitations
This calculator implements an experimental model: upgrade chance = strands × higher-tier natural weight ÷ (2 × side pool weight), capped at 100%. Successful destinations use separate positional weights of ×1, ×2, ×3, starting with the highest eligible tier. Selected modifiers do not reduce each other’s chances.
Only natural equipment affixes are supported. Crafted, essence-only, elevated, fractured, veiled and legacy modifiers are outside this model. Tier availability follows item level. Pools include base restrictions, influences and generation-weight multipliers. The 100-strand game limit is enforced; higher guarantee breakpoints are shown as unreachable.
