Results

DPS vs Great Olm

Hybrid armour

For multi-style bosses. Pick the styles you'll use and how many gear slots you're willing to switch — fewer switches share more armour (easier to play), more switches push each style toward its best gear. The weapon always switches.

Styles

Connect your bank (sync from the plugin) to build a hybrid setup from your gear.

Boss mechanics

Have it Missing Info
  • Multiple gear styles required
    Olm has 3 limb phases (head + 2 hands) plus a leg phase. Best practice: Tbow + Masori for head (high magic), Scythe for hands and legs (slash). Sometimes magic for head with Sang/Shadow.
  • Prayer flick Olm's autos
    Olm rotates Magic → Ranged → Magic → Ranged auto attacks during head phase. Flick the matching protection prayer.
  • Dodge specials: crystals, lightning, acid pools, falling boulders
    Each cycle Olm uses 2-3 specials. Crystal Burst (target lock), Acid (pools of corrosion), Lightning (chase line), Burning rocks (top of room). Memorise the cycle.
  • Phase: head → both hands → head → legs (repeat)
    Olm has 4 visible phases per cycle. Head must be DPS'd while hands are alive, but only takes damage when both hands are inactive. Kill hands first to enable head DPS.
  • Brews + restores
    Sara brews + Super restores. 4-6 brews + 4 restores typical for solo.
