About Big bones
"Ew it's a pile of bones."
Big bones are the F2P prayer staple, dropped by hill giants, moss giants, fire giants, ogres, cyclopes, and several jungle and cave-dwelling humanoids. Each bone grants 15 Prayer XP buried, 52.5 at the Chaos Altar or Gilded Altar with two burners lit, and 60 at the Ectofuntus.
Hill Giants under the Edgeville Dungeon are the iconic F2P prayer XP source. Ironmen frequently bank big bones for late-game Chaos Altar runs.

History (2)

Chaos Altar mechanics introduced via Zeah added a major demand sink.
- 2001-01-04
Released as part of the original prayer training drop tables.
Market Strategy
- Hill giant kill volume is the dominant supply driver.
- Cost-per-XP at the Chaos Altar is the demand benchmark.
- Bonecrusher meta and gilded altar housing pushes consistent uptake.
Trading Tips
Buy bulk during low-traffic hours: 3,000 limit fills fast.
Watch dragon bone price gaps: when dragon XP/gp inverts, big bones spike.
Stock up before double XP weekends — prayer demand spikes dramatically.
