Echo crystals are a drop received from participating in the Fortis Colosseum. It is used on a pair of guardian boots to create echo boots, which gives it an additional +2 prayer bonus and a passive recoil effect.

Each echo crystal added to the boots gives it 6,000 recoil charges.

The cumulative drop rate for at least 1 crystal if you complete all 12 waves is approximately 1/12.44

The cumulative drop rate for a multiple crystal drop if you complete all 12 waves is approximately 1/120.72

The expected amount of crystals if you complete all 12 waves is approximately 1/10.46
