Gehenna is where VAMPIR puts its open PvP: zones with different monster levels, a 200-player cap, an entry ticket to get in, and a currency called Gehenna Points that only the merchant in town takes. Elite Dungeon is the cross-server version: six servers thrown together for three hours a week to fight over hunting spots under a curse that stacks to seven, with one buff per zone that anyone can steal.

Entry Gehenna entry ticket
Cap 200 players
Zones Several, with different monster and boss levels and different rewards
Rewards EXP, items, Gehenna Points
Points Spent at the Gehenna Points merchant in town
Info Zone monster and boss details shown on entry

Trinity, the crafting and trading resource, comes mainly from PK fields according to Netmarble's economy notes, and Gehenna is that field. Go in with a party, pick the zone whose monster level you can actually clear, and read the boss info on entry before you commit to a spot.

Elite Dungeon: six servers, three hours, one curse

Elite Dungeon rules
RuleDetail
Matching Six random servers, on the server-group shuffle schedule
Time 3 hours a week; more can be bought with charge stones
Cradle of Radiance Hunting spots to contest; the Curse of Radiance applies on entry and stacks up to 7
Resistance Night's Protection Potion: 1 for 10 minutes; Elite Dungeon Seals: up to 8; extra resistance becomes boss damage
Forbidden Territory Opens free when the 3-star boss Lucef spawns; 2-star Necador and Valdemar appear at Lucef HP thresholds
Slaughter Altar One holder per zone: +7% damage, +15% attack speed, 10 minutes; position shown on the map; stolen in PvP, timer resets to full

The Slaughter Altar buff is a target painted on you: the map shows the holder's position and taking it off someone resets it to the full ten minutes. Hold it with a group or expect to lose it. Two-star boss kills in the Forbidden Territory pay clan buffs that help against Lucef, so the order is Necador and Valdemar first when they show.
