Ur-Sek

Natural elements OrganicPlasma

Ur-Seks are, in truth, two distinct creatures that coexist in permanent symbiosis. The two merged over a hundred thousand years ago, when Solum was still a luxuriant planet made up of jungles and oceans.

Element affinity

Ur-Sek evolves along two natural elements.

Organic

Highly effective against Lesion-spawns and Ancients.

Poison

Up to 15 stacks of Organic damage over time: low per-tick damage, but it lingers the longest.

Slow

Slowed enemies move and attack slower, scaling with the number of stacks applied.

Plasma

Effective against all factions.

Disintegrate

Up to 5 stacks with no damage over time; every stack beyond 5 triggers a Plasma overflow for massive damage.

Float

Floated enemies hover in the air for a few seconds before falling back down.

Modules

Gold marks the modules unlocked by the Golden Egg mutations.
