How many kills for each drop? (KC milestones)
Every kill is an independent roll with no pity timer, so your chance of having a drop by a given kill count is 1 − (1 − rate)kc. Here's when you cross the 50%, 90% and 99% marks — handy for checking how dry you are:
| Drop | 50% | 90% | 99% | Average |
|---|---|---|---|---|
| Elder venator fang | 231 | 766 | 1,532 | 333 |
| Crimson kisten | 361 | 1,197 | 2,393 | 520 |
| Maggot marquess (pet) | 2,426 | 8,058 | 16,116 | 3,500 |
You'll have a weapon unique (fang or kisten) roughly every 1/203 kills — a 50% chance by ~141 KC. Want it for your exact KC? Plug it into the simulator.

Requirements & how to reach the Maggot King
The Maggot King is a solo, instanced boss in Vampyrium, unlocked by completing the quest The Blood Moon Rises. At combat level 741, it is the most mature and strongest form of the ur-maggot. Each fight is instanced, so you take on the boss one-on-one and interact with its corpse afterwards to claim loot.
Take-eggs vs open-stomach
When the Maggot King dies it leaves a corpse with two choices. Open-stomach rolls the normal drop table shown above — this is the standard way to farm loot. Take-eggs forfeits most of the normal loot in exchange for one of six maggot eggs and a boosted chance at the Maggot marquess pet. The two are mutually exclusive per kill, so this simulator models the standard open-stomach loot path.
