The Deimos Therid is a large Infested Ancient that is capable of shooting orbs of cobweb.
Occasionally, the Deimos Therid will stand still and create a ball of webbing to throw it at the nearest player. The ball will cover an area on impact and slows nearby players similar to Tar Mutalist MOA's tar puddle, except it cannot be destroyed.
After not taking damage for 10 seconds, the Therid will start to regenerate 2% of max health per second.
Deimos Therids possess Damage Reduction that scales depending on your weapon's DPS excluding critical hits. DPS is calculated by

Where the proc damage is the per tick damage of the corresponding proc, with health/shield/armor modifiers taken into account.
Note that unlike the DPS controller for normal damage, the one for proc damage takes critical hits into account.
For heat procs, the proc damage in the above formula is the accumulated value of all the previous heat procs.
