Rarity Guards

Rarity Guards are optional protection items. One guard is consumed for each upgrade attempt. They do not affect Orb extraction.

Silver Rarity Guard

ID 40943 - Silver protection

+10% success, -1% break risk

Low level creatures: rats, trolls, rotworms, minotaurs, orcs, amazons, scarabs and similar monsters.

Golden Rarity Guard

ID 40940 - Gold protection

+25% success, -2% break risk

Medium creatures: dragons, ancient scarabs, giant spiders, banshees, necromancers, black knights and similar monsters.

Diamond Rarity Guard

ID 40941 - Diamond protection

+50% success, -4% break risk

Strong creatures: dragon lords, frost dragons, hydras, heroes, warlocks, behemoths and strong Pits of Inferno creatures.

Demonic Rarity Guard

ID 40942 - Demonic protection

Guaranteed success, 0% break risk

Very strong creatures and bosses: demons, juggernauts, undead dragons, hellhounds, Ferumbras, Orshabaal, Morgaroth and other major bosses.

Chance Calculation

Without Protection

The system uses the base success and break values from the selected rarity stage. If the upgrade fails, the Orb is consumed and the item keeps its current rarity.

With Protection

Silver, Golden and Diamond Guards add their success bonus and reduce break risk. Demonic Guard guarantees success and removes item break risk for that attempt.

Success chance is capped at 100%, and item break risk can never go below 0%.

Orb Extraction

Orb Extractor

Extracts Orbs from an item with rarity. The extractor has a 50% chance of breaking after a successful extraction.

Perfect Orb Extractor

Extracts Orbs without breaking. Extraction does not require gold and ignores Rarity Guards.

Important Notes

The item, Orb or Extractor, and optional Rarity Guard must be in your main backpack.
Most combat monsters with loot can drop one of the four guards according to their difficulty.
Passive creatures with no experience do not drop Rarity Guards.
Always check the module preview before confirming an upgrade.
