We introduce a tier of high-value materials based on iconic game "memes" and elements. These materials boast greatly inflated base stats and powerful, situational traits that directly reference their source material. Expect a heavily customized, late-game experience where a tool's performance is tied to the lore it embodies.

such as
Narcissus-Deals  large damage to targets with less than 15% remaining health.
Sprb-All non-material-specific Modifiers applied to this tool   are   more effective
SteinsGate-The ability to change the past. A powerful "cheat death" mechanic, saving the player from the "Bad End" at the last moment
