Resonator

Resonators are currency items that allow crafting rare items similar to Orb of Alchemy or Chaos Orb, but can be socketed with Fossils in order to change their crafting behavior. Fossils cannot be unsocketed once all the resonator sockets are filled.

WARNING: Despite the similar wording to chaos orbs, using a fossil + resonator on an item with a meta-crafting mod (such as "prefixes cannot be changed" or "cannot roll caster mods") will ignore that mod and overwrite existing prefixes and suffixes ignoring any restrictions.

There is an older variant of this item class available Delve Socketable Currency which will be converted to the new item class upon pickup. The old variant is no longer obtainable.
