From Halopedia, the Halo wiki
The Banished utilize modified Wraiths with additional armor plating and spikes, tabbed corners on new plates, energy shielding, and raw metals and "war paint" to reflect the Banished's aggressive mentality.
Crew and complement
Banished Wraiths are armed with a plasma mortar and twin plasma cannons for use against ground and air targets. The plasma cannons are hidden underneath the armor.
Halo Wars 2
Wraiths can be built at the Foundry by all Banished leaders. Unlike its Covenant counterpart from Halo Wars, the Banished Wraith in Halo Wars 2 starts off with an energy shield by default. Wraiths do well against infantry and vehicles, and okay against aircraft and structures. In Blitz Wraiths cost 110 energy, Ironclad Wraiths cost 140 energy, and Terror Wraiths cost 150 energy. Ironclad Wraiths agro all nearby damage from enemy units and Terror Wraiths reduce enemy units armor.
