They may be released for Divination experience, with the amount awarded dependent upon the player's Divination level. This is split into tiers corresponding to the different levels at which divine energy are unlocked (see below for exact experience values). The experience gained is also affected by boons unlocked, which give a permanent 10% increase for each "tier". Only the boon for the player's highest available energy will affect the experience gained. So this means that if the player reaches a new tier, the higher tier would be used instead even if the last tier is more experience per protean memory with the previous boon unlocked (only if the player hasn't unlocked the boon for the new tier). Memory strands can be acquired whilst using protean memories.
