Season levels and rewards#
Health and all attack-damage values are species bases, not final damage. Health scales by 1.065^(level−1) and damage by 1.05^(level−1), also modified by server strength. Season elites multiply health by 2.5 and damage by 1.3 before additional elite abilities. Base kill XP is the coefficient × (2 + 0.4 × monster level), then modified by elites, server rates, damage contribution, level-gap reduction and weakness. Summoned helpers award no season XP.
Spawning & habitat#
Does not spawn independently. Created by summoning or splitting from: Bog Hag
Behaviour & abilities#
- Applies poison for 2 s.
Drops#
| Item | Quantity | Entry roll | At least 1 |
|---|---|---|---|
| Slimeball | 0–1 | 100% | 50% |
These are unscaled base rolls. A quantity of zero yields nothing. Elite/area modifiers, bag space and applicable material limits affect the result; a kill is not a guaranteed drop.
Summoned/split forms are not independent natural spawns and do not use the natural-hostile seed roll; do not treat them as full natural encounters.
Strategy#
Clear the nearby leeches when they block movement, then return pressure to the summoner.
City siege vs wilderness#
This creature (or its summoned/split form) can also appear in the live city siege. The figures above are wilderness base definitions; siege strength, targets and loot use separate rules.
