Yttrium

Category:Resources
A rare-earth element used in the fabrication of plasma turret controllers.
Used in: All Plasma turret weapons (tiers I, II, and III)
(spoilers!)
 
Common sources: Bonuses from surveying Anomalies, destroying enemy ships using plasma weaponry, purchases from Trade factions on the cheap (e.g. Ermyr Defenders, Island Traders)
Remarks: If you intend to focus on plasma weaponry, you are expected to need no more than perhaps 650 Yttrium for the entire game. An exception is if you plan to take advantage of trade with Wiskamug for his system components. He frequently charges 100+ Yttrium per artifact, and so you might need 1200 Yttrium beyond your own use.
