Gemstone Crab
Combat level 160
Not really a boss: a shared AFK training target in the Tlati Rainforest. Its health bar drains on a ~10 minute timer regardless of damage dealt, then it burrows and moves. The 16 players who dealt the most damage get to mine three uncut gems from the shell.
Requirements
- Varlamore access (Tlati Rainforest)
- Any combat level
Pointers
- XP is 87.5% of the normal rate, but downtime is near zero, so effective rates beat regular crabs.
- The health bar is a timer, not a damage bar. You are competing for a damage leaderboard spot, not a kill.
- It has no defence stats, so any style connects. Bring your highest-DPS setup, not your most accurate one.
- It attacks with crush on a 7-tick cycle. Protect from Melee makes this fully AFK.
- Three spawn points via caves; hop if one is dead or overcrowded.
What the sim brings here
Every worn slot and every inventory row below is the combat simulation's own output, at the style it ranks fastest for each account tier. Each line carries the channel that chose it: sim means the model solved it, and inherited means the value came through from the hand-authored loadout the solver starts from. Riding through a generator does not make a value derived, so those are marked rather than presented as the model's answer. A line marked unattributed carries a channel the model's own vocabulary no longer declares, so no word is put on it at all rather than one being read off the channel's spelling. Where the model has not answered a row, its own refusal is printed instead; where it has answered a row it doubts, the answer is printed with the doubt attached rather than withheld.
The model declines to name a best style at this encounter: the model could price 0 styles at this fight, so there is nothing to rank one against. Every style it has either an answer or a stated reason for is listed below, rather than one being chosen for it.
No loadout: the model named no build row for this encounter at any tier, so there is no per-row refusal to print below either. This encounter has no kill to price: the health bar is a relocation timer, not a health pool: it depletes on a clock and is not affected by player damage at all.
What the model holds about this encounter instead of a kill:
- The reward is top-16 damage rank, mined from the shed shell, not a killing blow.
- Hitpoints as stated by the source: INFINITY.
- The model flags its own source here: the page states both and says they contradict; neither is used.
