Ortholysts are Sentient drones of near skeletal appearance, with two additional, larger appendages on their backs. Although they possess armcannons for closer ranges, they will try to keep their distance to enter a stationary mortar form.
In their stationary mode, they will launch two projectiles in an arc, which at their highest point will burst into 3 homing projectiles each. They will stay in this mode even under fire, but will return to their mobile form when an enemy comes too close.
Damage Adaptation[]
As a Sentient, Ortholysts have the ability to adapt up to 4 damage types from attacks: a Sentient's health is gated such that upon its hit points falling below a fixed percentage, it will grant resistance to the damage type it has received the most. The Sentient will adapt to damage once per health gate, at the percentages listed below:
- First gate: 25% Health lost.
- Second gate: 45% Health lost.
- Third gate: 65% Health lost.
- Fourth gate: 80% Health lost.
Subsequent adaptation will be done in descending order of damage proportion for each health gate. A single Sentient can adapt against a maximum of 4 damage types even if another Sentient transfers their adaptation, and Sentients will still receive full damage from any damage that exceeds their health gate before adapting.
On adapting to a damage type, the color of the glowing core on their chest changes to the corresponding damage type they recently adapted to, along with displaying the icon of said damage type below their health gauge.
The adaptation decreases in effectiveness the more damage types it resists.
- For the first adaptation, the Ortholysts will resist the damage type by 90%.
- For the second adaptation, the Ortholysts will resist the damage type by 80%.
- For the third adaptation, the Ortholysts will resist the damage type by 75%.
- For the fourth adaptation, the Ortholysts will resist the damage type by 70%.
Using the Operator's Void Beam, 
Excalibur Umbra's 
Radial Howl, a rank 40 
Paracesis, 
Shedu's pulse on expending all ammo, or 
Xaku's 
Xata's Whisper will remove and reset all their acquired damage resistances. Sentients can still regain their resistances, however, the aforementioned abilities and weapons will always be able to remove them.
The Ortholysts also receive another 40% resistance to the damage type at each adaptation, which stacks multiplicatively with the previously listed ones. These resistances cannot be removed by any of the methods listed above.
The damage gating also prevents Ortholysts from being killed in one shot, as the maximum percentage of health removable in one instance is:
- 25% at full health
- 20% between 75% & 55% max HP
- 20% between 55% & 35% of max HP
- 15% between 35% & 20%, after which there is no limit and the Ortholysts will take damage normally at every instance
