Summon your optimus Omicron minion. Minimum proportions, maximum performance.
As part of an initiative to downsize themselves, the Omicrons created this miniaturized, full-featured unit as a test prototype. Alas, the siege matrix Stigma-4 ceased to function shortly thereafter, and it never reached the mass production stage.
How to obtain:
Dungeon -- The Stigma Dreamscape
Deep Dungeon -- Eureka Orthos - Bronze/Silver Sack
Occult Crescent -- South Horn - Silver Coffer
