The Perihelion Emblem is a Lunar Emblems from WeaponOut that increases throwing damage based on the current weapon equipped. Whilst equipped, this emblem creates a green glow and trail from the player's hand capable of providing light, although this effect can be disabled.
Unlike the other Lunar Emblems, the Perihelion Emblem can be crafted before fighting the Moon Lord, due to the lack of real throwing weapons past hardmode, and no dedicated emblem.
Should you be playing with the Thorium Mod, then the Perihelion Emblem is only obtainable post-Moon Lord, as the other recipe is removed from the game.
This emblem is 10 cheaper than the others.
It boosts the Rogue class weapons from Calamity, and gives the weapons more range.
A Glaive (rogue weapon) that does 45 damage would do 263 damage with this emblem.
