Prices are from the Power Up Store on BianKO's own site. The forum price list from April 2, 2025 has the same numbers, so cospre prices haven't moved. This tab is KC only; there's no AB price.
Cospre certificate prices
| Piece | Store name | Site price | Forum (April 2, 2025) |
|---|---|---|---|
| Valkyrie helmet | Valkyrie Helmet Certificate | 890 KC | 890 KC |
| Valkyrie armor | Valkyrie Armor Certificate | 990 KC | 990 KC |
| Bahamut helmet | Bahamut Helmet Certificate | 890 KC | 890 KC |
| Bahamut armor | Bahamut Armor Certificate | 990 KC | 990 KC |
| Gryphons helmet | Gryphons Helmet Certificate | 890 KC | 890 KC |
| Gryphons armor | Gryphons armor Certificate | 990 KC | 990 KC |
| Yeniceri helmet | Yeniceri Helmet vouchers | 890 KC | 890 KC |
| Yeniceri armor | Yeniceri armor vouchers | 990 KC | 990 KC |
| Pathos gloves | Certificate of Pathos Glove | 600 KC | 600 KC |
The Yeniceri pieces are listed as "Yeniceri Helmet vouchers" and "Yeniceri armor vouchers", while the other three sets use "Certificate". Store cards only show name, type and weight, so the site doesn't list what stats or bonuses any set gives. All four sets cost the same.
Cospre from the packages
The VIP Package (1,500 AB) and Farm Package (1,100 AB) both contain Valkyrie Helmet Certificate, Valkyrie Armor Certificate and 2x Pathos Gloves. The cospre part is identical; the packages differ on premium, fairy, tattoo and KC. Bahamut, Gryphons and Yeniceri only come from the store, piece by piece.

Does cospre drop?
Two containers on the exchange page list Valkyrie and Pathos certificates. The figures are the rates shown on the site; in these containers the percentages don't add up to 100%, so read them as relative odds.
| Container | Certificate | Rate shown on site | Mob that drops the container |
|---|---|---|---|
| Random Item Exchange Gem | Valkyrie Helmet Certificate | 0.006% | Pride (5801) basic drop |
| Random Item Exchange Gem | Valkyrie Armor Certificate | 0.006% | Pride (5801) basic drop |
| Random Item Exchange Gem | Certificate of Pathos Glove | 0.006% | Pride (5801) basic drop |
| Golden Star / Red Bow / Tinsel Ornament | Valkyrie Helmet Certificate | 0.005% | Snowman (2701, 2702) |
| Golden Star / Red Bow / Tinsel Ornament | Valkyrie Armor Certificate | 0.005% | Snowman (2701, 2702) |
| Golden Star / Red Bow / Tinsel Ornament | Certificate of Pathos Glove | 0.005% | Snowman (2701, 2702) |
Bahamut, Gryphons and Yeniceri certificates aren't in any exchange list. Mob pages don't show zones, so the site doesn't say where Pride (5801) or the Snowman entries spawn. The rest of the Random Item Exchange Gem list is covered in a separate guide.
Hiding Pathos and Valkyrie with F10
One of the OASIS ARTY features is an "advanced F10 system". The forum topic from March 30, 2025 lists the effects you can hide as "Skill Effect, Object, Emblem, Cape, Pathos, Valkryie", so Pathos and Valkyrie visuals can be switched off in crowded fights. The topic body wasn't archived, so the exact setting isn't documented.
Paying in KC
KC comes from converting AB at 10 AB = 500 KC, or 20 AB = 1,000 KC. The same Cospre tab also sells the KC vouchers, Voucher for Magic Bag (490 KC) and [VIP] Vault key (999 KC).
