Mythic Loomithar Guide & Raidplan w/ Visuals

We’ve got the kill in the books—below is the plan we used and what we’ll keep running with.

TL;DR

  • P1: Tanks line Piercing Strand into wards → kill one Tangle → run out for Overinfusion Burst. Tethered players snap Infusion Tether at the wall; place Living Silk tight.  
  • Mythic: Four Infusion Pylons—fixed teams rotate at 5–7 stacks (Hyper Infusion). Missing a beam = Excess Nova. Two rings per Lair Weaving; both tanks hit a ward.  
  • P2 @ ~50% (Unbound Rage): drag boss clockwise; soak Writhing Wave with 5+ (alternate groups); spread after Arcane Outrage ends; Lust and finish before space runs out.  

Phase 1 (stationary at the loom)

Core loop

  • Lair Weaving spawns a closing ring of Infused Tangles. On Heroic/Mythic these are shielded by Woven Ward. Tanks must break the ward by lining Piercing Strand into it (back-to-back strands = swap each cast); then kill one Tangle to make the gap.  
  • Infusion Tether targets several non-tanks; run to the outer edge to snap it and drop Living Silk puddles—tight and near the wall to save space.  
  • At 100 Energy, sprint out for Overinfusion Burst (giant room blast).  
  • Background damage/visuals: Arcane Overflow (raid DoT) and Primal Spellstorm (projectiles). Healers keep ramps ready.  

Mythic changes

  • Infusion Pylons activate around the room; stand in the beam to intercept. Rotate 3–4 players per pylon and swap at ~5–7 Hyper Infusion stacks. Missing a beam triggers Excess Nova (heavy raid damage). Assign four fixed soak teams.  
  • Lair Weaving spawns two collapsing rings; each has a Woven Ward. Both tanks must hit a ward with Piercing Strand (one inner, one outer) every pattern.  

Phase 2 (boss drops at ~50%:

Unbound Rage

  • Boss becomes mobile, takes increased damage, and the center floods with Arcane Ichor—drag clockwise along the outer wall to preserve space.  
  • Writhing Wave (frontal) must be soaked by ≥5 players; alternate two groups. Failing the soak applies Writhing Swathe (absorb shield) to the boss.  
  • Arcane Outrage is a raidwide channel with knockback; spread 6y when it ends (small explosions) and move the boss off new ichor. Plan healer externals/ramp for Wave → Outrage overlaps. Lust here for the burn.  

Role notes

  • Tanks: Aim Piercing Strand away from raid; on Mythic, coordinate who hits inner/outer ward each pattern. Swap on every Strand pair.  
  • Melee/Ranged: Delete one Tangle after wards break; watch Living Silk lanes; commit to assigned pylon teams on Mythic.  
  • Healers: Constant Arcane Overflow + Spellstorm in P1; big CDs for Writhing Wave + Arcane Outrage overlaps in P2; spot-heal tether breaks.  

Common wipe points to watch

  • Late ward breaks → ring roots → Overinfusion Burst deaths.
  • Missed pylon beams → Excess Nova cascades.
  • Under-soaked Writhing WaveWrithing Swathe + space loss.
