its the Abyssal Devil (level 105) that gives the spars.

Devil's Spar Piece, Clear Devil's Spar, Cyan Devil's Spar, Orange Devil's Spar, and Green Devil's Spar.

you could ask the Trojan War winner if he/she could trade soem to you, but its unlikely. the last winner that i know of was a level 109 Trojan War winner. i do not recal his name, nor do i know what server hes on.
