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 | 36 | 5 | 90 | 6.5 | 43.2 |
| 10 | 63.5 | 7.8 | 158.6 | 10.1 | 108 |
| 20 | 119.1 | 12.6 | 297.8 | 16.4 | 180 |
| 30 | 223.6 | 20.6 | 559 | 26.8 | 252 |
| 40 | 419.7 | 33.5 | 1049.2 | 43.6 | 324 |
| 50 | 787.8 | 54.6 | 1969.6 | 71 | 396 |
| 60 | 1478.9 | 88.9 | 3697.2 | 115.6 | 468 |
Before server strength, area danger, armour and resistances; an elite’s extra abilities are on top.
Spawning & habitat#
| Rule | Details |
|---|---|
| Location | Caves |
| Time | Light-based; dark caves can qualify day or night |
| Pack size | 1 |
| Y restriction | 16 ≤ Y < 40 |
Underground generation bypasses surface biome filters, so suitable caves beneath other biomes can qualify. Y restrictions, lighting and space requirements still apply.
Spawning, light and season monsters — light, protection, player distance and population can still prevent a spawn.
Behaviour & abilities#
- Climbs walls.
- While hunting, lays a Egg Sac every 10 s, at most 3 at once.
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.
Eligible natural hostile kills also roll 3% for a seed, uniformly selected from ten types. Recipe rules: Cooking levels and costs
Strategy#
Break each sac as soon as it is laid; sacs still hatch after she dies. Spiders hatched this way give nothing when slain.
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.
