Demonic gorillas
Zenyte shards and prayer-flicking practice
Prayer-switching PvM in the Crash Site Cavern. The profit is spiky: most of it rides on the zenyte shard, so some hours are quiet and then one drop pays for the whole session. Great value if you can flick prayers cleanly, and a rite of passage before heavier PvM.

Approximate profit after input costs, from the OSRS Wiki money-making guide as read on 2026-08-03 (assumes ~70 kills/hr). It isn't measured or recalculated by ScapePath, and your rate depends on your gear, efficiency and current prices. The figure is over 90 days old, so prices have probably moved. Source.

Why choose this method?
- Ranks #3 of 18 bossing methods by profit on the sourced figures.
- Cheap to set up: about 300k.
- Every kill also counts toward your Demonic Gorillas kill count and its unique drops.
- Worth doing on an Ironman: it gathers its own inputs or gives untradeable value.
- It pays you while you train Slayer, which many accounts do anyway for its unlocks.
Who should skip this method?
- It needs constant attention. For something more relaxed in the same category, look at Kraken.
Tips
- They switch protection prayers every few hits — match yours or the damage adds up fast.
- The zenyte shard (~1/300) is where the money is; don't judge a session by one dry hour.
- Bring a Zombie axe or Arclight-style spec to speed early kills while learning.
