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, 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.

Legendary URRs

URR	Base Chance per Land	Use
Titanium Splinter	0.027%	Substantially increases base upgrade chance from Epic to Legendary.
Chaos Seed	0.027%	Can be consumed to reroll item quality and other events.
Dawnstone*	0.0075 - 0.025%	Can be consumed to increase quality of an item by 10.
Primal Loam*	0.0075 - 0.025%	Can be consumed to boost resource production by 50% for 72 hours.

^{* Can only drop if a Shovel is equipped - chance based on rarity tier and quality of the Shovel}

Mythic URRs

URR	Base Chance per Land	Use
Phoenix Feather	0.0017%	Substantially increases base upgrade chance from Legendary to Mythic.

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

Example Calculation A

10 Lands staked no Shovel no Idol of Axomamma

Chance to dropPhoenix Feather = 0.0017% * 10 = 0.017% Chance to dropTitanium Splinter = 0.027% * 10 = 0.27% Chance to dropChaos Seed = 0.027% * 10 = 0.27%

Chance to drop any URR: 0.557%

Example Calculation B

10 Lands staked Rare Shovel (100 Quality) = 0.0275% Chance per Land (0.01375% each URR) Rare Idol of Axomamma (50 Quality) = 3.75x Multiplier

Chance to dropPhoenix Feather = 0.0017% * 10 * 3.75 = 0.0638% Chance to dropTitanium Splinter = 0.027% * 10 * 3.75 = 1.0125% Chance to dropChaos Seed = 0.027% * 10 * 3.75 = 1.0125% Chance to dropDawnstone = 0.01375% * 10 * 3.75 = 0.5156% Chance to dropPrimal Loam = 0.01375% * 10 * 3.75 = 0.5156%
