Quest The Light Within

Crystallise is a Seren spell unlocked by The Light Within. It is a skilling spell that locks a skilling node to increase experience gain by 50% at the cost of preventing resource yield. This can be further increased to 87.5% by activating the Light Form prayer, and the bonus does stack with bonus experience and experience-boosting equipment. It can be used with Mining, Woodcutting, and Fishing spots, or full Hunter box traps.

The crystallised resource will last 30 seconds from the time the spell is cast, not from when you engage with the resource. This means that the spell will wear off whether you engage with the resource in those 30 seconds or not. If another player is using the same resource node, it will deplete as normal, but the Crystallise spell's effect and timer will "pause" until the node refills. If a Fishing spot moves, the spell will move with it.

Once the spell has worn off you will collect one of the resource as you would if you had not cast the spell.
