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.
| Level | Health | Melee damage | Elite health | Elite melee | Kill XP |
|---|---|---|---|---|---|
| 1 | 4 | 0 | 10 | 0 | 2.4 |
| 10 | 7.1 | 0 | 17.6 | 0 | 6 |
| 20 | 13.2 | 0 | 33.1 | 0 | 10 |
| 30 | 24.8 | 0 | 62.1 | 0 | 14 |
| 40 | 46.6 | 0 | 116.6 | 0 | 18 |
| 50 | 87.5 | 0 | 218.8 | 0 | 22 |
| 60 | 164.3 | 0 | 410.8 | 0 | 26 |
Before server strength, area danger, armour and resistances; an elite’s extra abilities are on top.
Spawning & habitat#
Does not spawn independently. Created by summoning or splitting from: Cave Broodmother
Behaviour & abilities#
- Rooted in place; does not walk.
- Hatches into 2–3 Cave Spider after 6 s unless it is destroyed first.
Drops#
This form has no ordinary item drops.
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#
It is fragile: break it with a quick blow or an arrow before it heaves and bursts. It hatches even if the broodmother is already dead.
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.
