Player versus player combat. Players can damage each other in open-world PK, duels, the arenas and guild battles, and chaos points now carry consequences.
Tournament arena. Brackets, betting, the match clock and prizes, with arena windows in place of the notice that the arena was being rebuilt.
Practice arena. One-on-one duels with a level band, an entry fee, win/draw/loss records and an item and coin wager paid to the winner.
Guild war. Challenge another guild, fight on the scoreboard, plunder and collect the rewards.
Dan battle. The guild-versus-guild arena on its own map, ending on the clock or on a wipe, with draws.
Job awakening. Jobs are reached through their quests, and an awakened job stays after you log out.
Helper system. Pair a new player with a mentor, and the pairing and points survive a restart.
Lucky stones and the gamble store. Monsters drop lucky stones, and the warehouse keepers open a store that sells items for them.
Quest scrolls, quest item drops and the summon card. The quest scroll shop sells, an auto-quest scroll starts the quest it names, quest items drop and the monster summon card works.
World change item and experience events. The world change item works, and game masters can run experience-rate events.
Server control panel. The website covers your account, characters, server status, news and support tickets, and staff can ban, kick, reset passwords and change server settings from it.
oldschoolops.com sign-in. An operator can let players log in with their oldschoolops.com account.
First administrator. A new server prints a one-time password that creates the first Super Administrator.
GoMMO Studio link. GoMMO Studio connects to a running server to show its status, players and log, run game master commands, spawn monsters, start play from a chosen spot and reload game data and NPC dialogs without a restart.
GoMMO Studio live tools. Over the same link Studio shows player heat, the economy and recordings, edits monster stats live, schedules events with experience and coin rates, and debugs NPC scripts.
Keyboard movement by default. The game starts in WASD movement, and Alt+K or the Options window still switch to click to move.
One server process. Login and the game run in one program, and the client connects to one address with no server-select screen and no extra second before entering the world.
Loading screen. The client shows a window with its progress straight away instead of nothing for half a minute.
Respawn. Respawning restores full health and mana instead of a tenth of each.
Staff commands. Game master commands are for staff now; players keep /help, /who and /info on their own character, and /help lists only what your level allows.
NPC conversations. All twelve script actions that used to close the dialog and do nothing now work.
Skill learning. The skill window's requirements are enforced, and gen capability is awarded on the authored curve, so early skills unlock sooner.
Login messages. A username was answered as a wrong password and the launcher showed a ban as "Server error"; the game now asks for the account email, and the launcher says the account is banned.
World chat. Messages sent to world chat were dropped and now reach every player.
Guild chat. Guild messages went to every player in the world and now reach the guild only.
Party chat and the party window. Party chat was dropped and the party window did not come back after a relog.
Guild names and emblems. They never showed over players and now do.
Chat bans. A mute silenced only world chat, never ran out, told the player nothing and ended at relog.
Silent refusals. Whispering an unknown name and casting a refused skill now say why.
Item option bonuses. Most options did nothing and some granted the wrong stat; they now match the tooltip.
Craft and upgrade. Crafting matched no real recipe and neither craft nor upgrade ever finished; both complete, and the result lands in the result slot.
Upgrade crash. Preparing an item for upgrade could crash the client.
Quest rewards. Coin rewards were paid as experience, and some quests could be completed without the items they ask for.
Mailed coins. Sending coins with /sendpost created them instead of charging the sender.
Shop quantities. Buying a quantity of zero handed over a free item, and a very large quantity got past the weight limit.
Server freeze at high levels. Raising a character to the top of the level range could freeze the whole server.
Appearance changes. A skin change is kept after logout.
Magic book. A book on its last use vanished on the server while the client still showed it.
Magic book and e-pack recharge replies. Their answers never reached the client, so using either got no response.
NPC hand-in window. Every click in it stopped the game sending your actions for five seconds.
Alt-tab. The client survives losing its display device instead of crashing or closing.
Dead characters. A dead character could still be walked around the world.
Chasing monsters. A chasing monster was drawn running faster than it really moved and kept snapping back.
