Ripa 'Moramee will be automatically deployed as soon as the player finishes their first Temple. If that Arbiter is killed the player can purchase another for 400 resources, but can only have one Arbiter at a time. Ripa uses dual energy swords in battle and cannot attack aircraft unless in rage mode.

  • Unique Unit: Suicide Unggoy - are able to blow enemies and themselves up with plasma grenades.
  • Fiendish Return - Allows the Arbiter to reflect attacks back at the enemy. Requires 400 resources and a tech level of 1.
  • Vicious Blades - Increases damage inflicted by the Arbiter. Requires 600 resources and a tech level of 2.
  • Ghastly Vision - Increases Fiendish Return reflection and equips the Arbiter with active camouflage. Requires 900 resources and a tech level of 3.
Leader ability - Rage

When activated, the camera locks onto the Arbiter, whom the player controls with the left thumbstick and attacks with the right. It will use up resources every second it is in use and can be upgraded at the Temple. Rage Mode allows the Arbiter to single out enemy units, lunge at them, and deal damage on them. A fully upgraded Rage increases the player's units' damage while the Rage is still active. This also affects allies, including allied UNSC units, boosting their damage.

Ability upgrades
  • Defiant Rage - Receive additional health for casualties inflicted. Requires 300 resources and a tech level of 1.
  • Spiteful Rage - Abilities cost less resources. Requires 500 resources and a tech level of 2.
  • Blinding Rage - Increases the Arbiter's and nearby allied units' attack power. Requires 700 resources and a tech level of 3.

Ripa 'Moramee is exclusive to himself and can be built at the War Council. Like other hero units the player is limited to one on the field at a time. Ripa performs well against infantry, vehicles, and structures, but only okay against aircraft. Once the Conduit Incarnate upgrade is purchased Ripa will perform well against aircraft. Ripa can only attack aircraft while using his Rage ability. Unlike his Rage ability in Halo Wars, his Rage in Halo Wars 2 does not allow to player to control him. However, it not longer costs resources to use, and instead lasts for a set time. In Blitz he costs 240 energy and features the Rush ability that eliminates spawn debuffs.



  • Be careful when utilizing Mass Stasis and Statis as both leader power can make any enemy and allies unit invulnerable to any attacks, giving both sides a chance to recuperate their army using any healing leader powers.
    • This also affects building as any production will be temporarily halted.
  • Power Surge is very useful in late-game, practically if the player constantly uses leader powers for advantage.
  • Note that the Arbiter is one of the few Leaders that does not have any active healing leader power. It is best to conserve the personnel wisely and use Stasis leader power for advantage.
  • Conduit of Rage is extremely useful for late games. Combined with Power Surge, Ripa 'Moramee's leader power can be the most difficult to handle for all Leaders.
  • Ripa 'Moramee's leader powers are generally designed to counter Isabel.
    • Additionally, Ripa 'Moramee is suitable to take on the Support Role due to its passive leader power that complements Stasis Leader Power.


  • Sangheili enforcers is one of the best Anti-Infantry and Building. With a large number, it will be very difficult to handle. Pair up with some of the allies anti-air and anti-building, practically UNSC Marines fitted with Combat Technician to cover each other's back.
  • With correct timing and place, Stasis and Mass Stasis can negate all of the enemy's leader power that deals damage to your allies.
  • If your allies have a healing leader power, use it immediately, as any units under stasis can be healed using a Leader Power.
  • If the enemy is using Isabel, use Stasis when your allies get hijacked through Ghost In The Machine. Not only her power will be wasteful, but it will also benefit your allies as hijacked units can't go anywhere.


  • Do not group up when attacking, as you may receive either Mass Stasis or Stasis Leader Power.
  • Isabel's Ghost In The Machine is ineffective when the enemy is using Stasis, rendering her Tier 5 leader power obsolete.
  • Units affected by Stasis are completely immune to damage, rendering a waste of resources when using offensive leader power.
