Data and calculation methods
RiftDen data sources, stat formulas and limitations of champion comparisons, duels and builds.
Patch 16.19.1 · Data updated:
Sources
Data Dragon supplies champion stats, abilities and items. CommunityDragon adds game coefficients, videos and skin details. Meraki Analytics supplies primary positions. Stories and regions come from Riot Universe.
Stat growth
At level n we use the base value plus growth multiplied by (n − 1) × (0.7025 + 0.0175 × (n − 1)). The bonus is zero at level 1 and seventeen growth increments at level 18. Attack speed uses its separate ratio when available.
Interpreting results
Base auto-attack DPS is attack damage × attack speed. Rankings exclude abilities, passives, items, critical strikes and player decisions. Effective health estimates durability against one damage type without penetration or shields.
Duels simulate auto attacks, armor and health regeneration; closing distance follows the selected setting. Abilities, runes, items and critical strikes are excluded. Winning the simulation does not predict winning a lane.
The editor combines base stats, known item stats and supported shard effects. Conditional passives and complete combat are not simulated. A personal tier list represents your own rankings rather than win-rate data.
