Ultra Rare Resources (URRs)

Needles in a haystack

URRs are very hard to come by, but once found offer unique benefits.

Every time an Architect claims the Resources of his staked Lands or the Influence of his patrolling Heroes, he has a chance to find an URR (only one at a time). This chance has a cooldown of 24 hours.

An Idol of Axomamma increases the chance to find URRs when equipped.

All URRs will also play a role as ingredients for certain recipes and blueprints.

Example Calculation A
