Step by step

  2. 02

    Prepare ordinary defenses and a useful Pentagram / Errtel setup for elemental combat.

  3. 03

    Assign objective and defense groups, then follow the current obelisk or occupation targets.

  4. 04

    Hold the required objectives and inspect ownership or reward status after the result.

03 / FROM THE FIELD

What makes the difference

Arca Battle is different from PvE Protector of Acheron, even though both involve elemental territory.

The supplied realm has ArcaBattle configuration; live registration and rewards remain authoritative.

Sources & realm rules

This guide is based on the supplied MU WAR S21 configuration and current client workflows. Custom chances, rewards, availability and item requirements are decided by the current client. Live realm timetable ↗.
