Copper

Copper is a Unique aura themed after the metal itself, with an unusually large number on its crafting entry. The roll chance is 1 in 29,000, so about 2,900 rolls at 10x luck, and a crafting entry lists 20,000 MasterHand. It was added in Eon 1-7. ender24_vfx and dracula1712 created it, and the in-game text calls it the oldest metal ever handled by civilization.

The model leans on science-class imagery. An orange-red vortex turns beneath the user from the outside in, orange lightning flashes in short intervals, light orange mist with small particles hangs around, the chemical symbol Cu appears on the torso, a solid copper bar is held in the right hand and a copper coil floats behind the left shoulder. The cutscene starts with a four-pointed orange star spinning clockwise before the orange glow reveals the aura. The font is Michroma, a squared futuristic face that suits the lab theme.
