Lord of Mysteries Offspring Guardian Boss Guide 2026

The encounter is 'Offspring Protection' in the English client, with 'Golden Orchard Guardian' printed under the health bar — the fourth boss of the May Manor Castle raid. The pull frame catches the raid stacked on the boss at 96.4% with the 'About to go Berserk' warning already ticking beside the bar, and the left-hand HUD reading 'Resurrection Count: 9/8+1'. Read both before you commit: the berserk clock is the real timer on this fight, and the resurrection pool belongs to all twelve players, so every death is a raid resource rather than a personal one.

The opening pattern is a wide earth sweep that covers half the arena, followed immediately by a straight-line slash that picks one ranged DPS and fires through them. The recording's rule is to leave the sweep and stand in the corner the line does not cross, so the second half never touches a teammate. The in-game subtitle names the swing — 'Earth, refine. Great Sword Slash.' — while a red 'Earth Tremor' tag sits on the boss, which is your cue that both halves of the pattern are still coming.

The second pattern paints an area around the group and then moves it — 'the affected areas will alternate, so get ready to switch,' as the narrator puts it. The footage catches the group's own callout in the chat box: stay near the boss so the red AoE locks on, then move through it once and do not get hit twice. One crossing is survivable; the same player clipping the same spot twice is how this pattern kills, so move as a body and keep the melee and ranged halves of the raid on the same side of the circle.

What follows the swap is a share-soak. The client prints the requirement itself — 'Split into two teams and gather to share the damage' over twin golden circles, with 'Requires 4 people to share the damage' underneath — and the narrator says the same thing in plain words: four players in each circle or it hurts. Fix your two groups before the pull. The circles are not flexible, and an under-filled one drops the whole hit on three players.

This is the clip the narrator tells you not to repeat. Standing in the wrong half of the sweep kills the recording player, and the frame shows the price: a resurrection prompt offering to 'awaken you from the Subconscious Ocean', plus a damage-source recap listing the killing blows as an earth ability and a golem hit from the boss, both landing in one window. The HUD has already ticked from 9/8+1 down to 8/8+1. Nothing in this fight is such a tight damage race that you cannot afford to move first — the sweep resolves before the line, so movement is free.

The pattern does not stop when the soak resolves. A follow-up sweep crosses the arena and the raid walks out of it on small heal ticks, with the HUD already down to 7/8+1. The narrator's instruction is explicit: the healer puts both teams back to full immediately, because the boss launches another attack straight after the raid-wide. While the group is still split in two, keep each team inside heal range of the other so the next hit does not catch one circle at half health.

The only hard number in the recording is the damage check. As of this run the creator measured 26k DPS on the butler dummy in the training ground and says all you need is probably around 18k. Both figures are one player's own parses, spoken on the recording rather than shown — no in-game meter appears anywhere in the footage — so hold them as community-reported targets [unverified] and sanity-check them against your own group's clear times instead of treating 18k as a published requirement.

The narrator's phase trigger is audio, not visual: when the professor starts talking, the third phase is about to go. The footage catches that line as an in-game subtitle — 'Professor: He will risk everything to guard the offspring of the Great Mother.' — with the boss at 45.4% and the arena still lit red. From the voice line the group has a few seconds to collapse onto the boss before the offspring appear, so use the subtitle as the countdown rather than waiting to see the spawns.

Once the offspring are up, the recording's rule is positional: stand behind them and keep rotating the camera as they turn. The frame at 41.7% shows what that looks like in practice — red offspring figures on both flanks, the boss staring the group down through the in-game line 'Offspring Protection is staring at you', and a 'Super Armor Damage Reflection' aura sitting over the pack. Staying behind the offspring is what keeps the raid out of the front arc while damage keeps flowing. The narration and the producer's burned-in caption disagree about which way that rotation goes, so the direction is logged as unverified rather than guessed.

The fourth pattern is the one the narrator says kills a lot of teams, and it is movement rather than damage: alternate between standing inside the ground ring and outside it while travelling counter-clockwise — the opposite direction to the previous phase. The frame shows the ring as the mechanic itself, a dark band on cracked red ground with the player sitting on its inner edge. Walk it slowly and continuously. Sprinting between the edges of the ring is what clips people, and phase four is where the raid's remaining resurrections disappear.

The last new pattern is a positioning puzzle. One player is aimed — the frame shows the red line already drawn across the arena, the boss at 34% and a golem add parked on the flank — and the group has to work out who it is, then stand where the line crosses no teammate while still landing damage. The narrator calls this the hardest pattern to position, and the practical version of that advice is to call the target out loud and let everyone else move, rather than expecting the aimed player to solve it alone.

Just before the final burn the encounter plays a short cut scene, and the narrator's instruction is to treat it as a timer: when the scene plays, the healer has to put the entire raid back to full as fast as possible, because the boss unleashes a map-wide attack the moment it ends. The frame catches the boss's line — 'Offspring Protection: Trespasser... die!' — with green heal ticks already landing on the group. Top the raid during the scene, not after it; there is no second window between the cut scene and the hit.

The raid-wide arrives as a single fire burst over the arena. The frame shows the raid standing inside it at 31.1%, the 'Super Armor Damage Reflection' tag still up on the boss, and the group chat asking for a spectator resurrection — the cost of one missed heal. There is no soak circle and no safe corner here, so the counter-play is preparation rather than movement: both teams at full when the burst lands, and everyone stacked tightly enough that group heals cover the whole raid at once.

Once the fifth pattern resolves, the encounter is over except for the damage — 'all you got to do now is DPS and you've already cleared this,' as the narrator puts it. The last-quarter frame shows the boss at 25.4% with the HUD on 1/8+1, one shared resurrection left for twelve players, so the final burn is exactly where you stop taking greedy lines. Keep the two teams stacked, keep heals rolling, and let the damage check close the fight instead of a corpse run.

The run ends in the game's own loot flow rather than a chest. A Group Auction window opens over the post-clear scene, listing the drops with starting bids and a short distribution countdown, next to the clear card for this player. The frames name the visible items — an Elemental Secret Rune Amulet, Cocoon Silk, Honor: Guardian Blade, and stacks of Defensive and Attack Material — which the recording never discusses out loud, so read that list as observed loot from one run rather than a quoted drop table.
