How to read these drop rates
These are the same Serenity loot rows shown on item pages. Main, charm and extra loot normally make separate rolls. When an encounter has a signature pre-roll, a signature reward replaces the common roll. Common-drop rates shown here include the chance of reaching that table. Empty slots are included in each pool's weights. A “1 in” rate is an average, not a guaranteed number of kills. Shared tables are conditional because additional rolls and equipment can affect their final chance. Scripts and encounter phases can award additional loot.
Combat levels come from the game cache. Statistics, Slayer advice, spawns and loot come from this Serenity server. Some encounters use scripts that override standard behaviour.
