Fiend War Basic Rules
Participants
The raid supports cooperative play with up to eight characters simultaneously, allowing for diverse party compositions. Strategic team building becomes crucial as different classes bring unique advantages to specific battlefield scenarios.
Time Limit
A strict 60-minute total time limit creates intense pressure throughout the raid experience. When this overall timer expires, participants automatically fail the Fiend War but receive compensation through Reentry Tickets delivered to their Mailbox.
Each individual battle within the raid features its own countdown mechanism. Missing these sub-timers triggers Failure penalties that accumulate and impact final reward calculations.
Party Formation
Restrictions
Raid organization follows a hierarchical structure where each character forms an independent squad. Battlefield capacity restricts entry to four squads per engagement zone, with automatic 4-squad unit creation at each battle commencement.
Fiend War: Battlefield
Normal Sectors function as contested territories where both player characters and Fiend forces can maneuver freely. These areas require constant awareness of enemy movement patterns and strategic positioning to control engagement flow.
Special Sectors represent critical strategic points that offer tactical advantages when controlled. Securing these locations often requires coordinated squad efforts and proper resource allocation.
Enemy Sectors serve as fortified invasion bases constructed by cosmic forces threatening Arad. These heavily defended areas demand precise execution and well-timed ability usage for successful assaults.
