Loadout

Results

DPS vs The Leviathan

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

1 missing
Have it Missing Info
  • Pray rotating styles
    Leviathan cycles Magic → Ranged → Melee in patterns. Flick the matching protection prayer each tick. Mistakes cost ~30 unprayed.
  • Skip across the lake stones
    During the underwater dive phase, navigate the stepping stones. Falling in deals heavy damage and resets you to the start.
  • Ranged is BIS; melee from the east
    Leviathan's lowest defence by far is ranged (50 vs 190+ for every melee style), so Twisted bow / a strong crossbow lead. If you melee instead, Scythe is best in slash — stand on his east side to avoid the tail sweep.
  • Food + brews
    Sara brews + Super restores.
