Using Devonian Island

Devonian rocks supply Red Jasper for Silver and the Dunkleosteus Shards for Kai’s quest batch. Kai and the Whirlpool are described behind or to the right of Devonian.

Practical questions

Does the Bronze reference cover every Devonian task?
The 8 October ladder associates Bronze with Devonian digging. The Kai guide separately requires Silver or better for Dunkleosteus Shards, so the specific quest condition stays attached to that material.
Where does the skull objective lead?
After accepting Kai’s quest, follow its pointer to the Mosasaurus Skull on Cretaceous and return. The skull destination is different from the Devonian NPC location.

Where to find Devonian Island: location, map route and unlock requirements

Is Devonian Island worth it? Best use and tier comparison

Visit for the eight Jasper pieces needed by Silver or the twelve-shard Kai batch. The task-specific Silver condition is not erased by the older Bronze/period label. A seed code, full coordinates or a numeric best-island income order is not supplied.
