How does Border Defense War (BDW) work?

Source / rights
BDW is 8 vs 8 and lasts 30 minutes. You score by killing enemy players and by carrying the Altar of Manes crystal from the middle of the map to your side; the side with more points at the end wins.
Entry needs level 65 and 5,000 NP. A sign-up window pops up when the event time comes, and if you die inside you wait 2 minutes.
Collection Race MOB vs PK
Collection Race [MOB] is a monster-kill race and [PK] is a player-kill race. On 23 June the CR (PK) reward pool gained Master items, Old accessories, Trina and +7/+8 accessories.
The CR Points you collect can also be broken for rewards; the list was refreshed on 24 July and the Master Item Box sits at the top of it.
Juraid, Chaos Dungeon and Forgotten Temple
These events have no fixed slot in the daily schedule; you follow their start time with the hourglass icon in game.
- Juraid Mountain: 8 vs 8 team fight, 30 minutes; standing still for 2 minutes gets you removed.
- Chaos Dungeon: no parties, everyone fights alone; it lasts 20 minutes and needs at least 18 players to start.
- Forgotten Temple: enter through the [Priest] Iris NPC in Moradon; monsters spawn every minute for 30 minutes.
- Funclass Event: everyone gets a random class and there is no level limit.
Moradon Gate events
Piana War, Zindan War, Snow War, Night Delos War, Mini Ardream, Mini Colony Zone and Ronark Land Base run on reduced maps. You enter all of them through the Moradon Gate, and inside there are Chaos Stones and event-only Collection Race quests.
