I'm too lazy to make fancy shops so i'll simply list everything:
Dragon Blood Stones x3350 = 3k ECs
Damascene Ores x205 = 24 EC each
Demonic Weapon Token x20 = 50 EC each
.
Boss Cards:
Random Boss Card x7 = 500 EC each
Harpy Wraith Card x4 = 500 EC each
Illusion Lord Card x3 = 300 EC each
Medusa Card x6 = 250 EC each
Avenger Card x2 = 250 EC each
Twilight Ancestor Card x2 = 200 EC each
I also got alot of AEU Books stuck on my WB, they're all 100 EC each. If you're interested here leave a reply, send me a forum message or message Emnesty ingame, im around between 10am-4am server time, depending on how bored i am. Happy gaming.
Edit: WTT 2 Atk lvl 10 Dex magic ring for 2 atk lvl 10 str magic ring. I don't add extra EC for that.
