Hi! I feel like I'll be asking for a lot in one go, so if you have a summon limit just let me know ;D; I also estimated a lot of these prices based on the current market value, so let me know if you'd like me to make any changes! I'd like to buy: Orders crest (350 gp) Wishing star (280 gp) Psychic Feather (320 gp) Rage Feather (380 gp) So for these 4 items, 1330 gp total? Let me know what you think! Thank you!
