Omniscient Voidstone is a Voidstone. Socketing Voidstones will progressively increase the tier of your maps on the Atlas of Worlds up to tier 16. Each Voidstone also grants a chance for a tier 16 map to drop as a tier 17 map.
Voidstone grants Tier 1-15 Maps found have 25% chance to become 1 tier higher. This stat stacks additively with similar stats from the Atlas Passive Tree; if the chance exceeds 100%, the excess chance instead applies to chance to be 2 tiers higher (to up to tier 16), and so on.[1]
Maps tiers scale based on the number of socketed Voidstones:
One Voidstone - Increases all maps on the atlas by +3 Tiers to a maximum of 16.
Two Voidstones - Increases all maps on the atlas by +7 Tiers to a maximum of 16.
Three Voidstones - Increases all maps on the atlas by +11 Tiers to a maximum of 16.
Four Voidstones - All maps on the atlas are Tier 16.
