Do the Costume Elven ears exist on the server? I've never seen them in the shop or anywhere else, and I'd really like to have them.
On the official Ragnarok Online item lists there is a Costume Elven Ears item defined — it’s a middle headgear that’s purely cosmetic and doesn’t give stats. That means the asset and the entry exist in the broader game data. What doesn’t always follow from that is that the item is actually obtainable on your particular server. Many servers don’t include every costume item in the shop or as an event reward, so even though it exists in the game’s global database you might never see it on your server’s cash shop, marketplace, or events. A lot of players notice this with various costumes: they’re “in the game” in a technical sense, but the server hasn’t enabled them for players to acquire. If you haven’t seen Elven Ears show up anywhere, it’s likely just not made available on your server yet.
If you really want to be sure, your best bet is to ask a GM directly or post in the server’s suggestions section. Sometimes items like that are planned for future costume rotations, seasonal events, or special promo boxes, but just haven’t cycled in yet. You can also try checking the in-game market or asking veteran players if it was ever obtainable in the past. Some costumes appear briefly and then disappear for months. If there’s enough interest, staff might consider bringing it back in a future update.
