O.R.C. Broodmother & Masked Fighter

The O.R.C. Broodmother & Masked Fighter is the second story boss of Grounded 2, a tier 3 duo fight that ambushes you in the Ominent Field Archives. The two attack together across multiple phases, with the Masked Fighter at times riding the Broodmother itself. Beating them is required to grow the key lime tree and unlock further progression, and they drop Broodmother Chunks used in crafting.

Two health bars, not one

The combined 4,375 makes this the largest health pool on the critical path, and the biggest one by some distance: the final boss, the Masked Stranger, has 1,875 on her own.

The Broodmother's stun numbers are the hardest in the game, and they are the reason this fight stops people. A threshold of 350 is 4.7 times what the two scorpion officers need, and the 120 second cooldown is 24 times their 5 seconds. Compare Skritch, the tier 4 fight at the bottom of the Sacrificial Pit: 9,000 health, but staggered at 100 on a 25 second cooldown. Skritch is a long fight you stay in control of. The Broodmother is a short one you do not. Plan on landing one stun, using it, and then fighting her honestly for two minutes.

Which is why the Masked Fighter is the half to kill first. She has 75% of the Broodmother's health, staggers at 90 on 20 seconds like an ordinary tier 3 creature, and takes +10% from Fresh while the Broodmother has no elemental weakness at all. Dropping her removes the mobile damage from the encounter and leaves you one slow target.

Neither half cares about Sour, both shrugging off 50% of it, and Water is docked 35% on both. That rules out the two things players tend to reach for in the Archives.

Both stat blocks were read off the Grounded Wiki's O.R.C. Broodmother page on 2026-10-27, which carries one infobox per half of the duo. See the full boss list for the other eight, and damage types for what Sour and Fresh do here.
