Min level 15 Max 15 players 20min Devil's Invitation, Devil Square Ticket 6 levels Devias
A timed PvE survival event. Players enter an arena where waves of monsters spawn continuously. Unlike Blood Castle there is no objective to destroy or item to return — it's pure damage, AoE, survivability, and efficient positioning. Kill as many monsters as possible, survive until the end, and earn experience and score-based rewards. PvP is disabled inside.

How to enter
- 1 Obtain a Devil's Invitation matching your level range (Devil Square 1–6)
- 2 Invitation is crafted in the Chaos Machine from: Devil's Eye + Devil's Key + Jewel of Chaos — Eye and Key must match the invitation level
- 3 Talk to Charon NPC in Devias to enter when the event opens

Entry items
Devil's Invitation
Devil Square TicketTactics
- Use a party if possible — more damage and buffs mean faster monster clearing and higher score
- Stand where your AoE hits the most monsters — don't chase individual mobs when you can hold a strong central position
- Prioritize survival over greed — dying usually means losing your chance to continue
- Use strong area skills — Devil Square heavily rewards AoE builds
- Bring enough mana potions — most classes lose efficiency without constant skill use
- Support Elf: keep buffs active, help with damage when safe
- Dark Wizard / Summoner: keep distance, use AoE control and damage
- Melee classes: avoid being fully surrounded if your defense is low
