DPS vs Dagannoth Rex

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.

Have it Missing Info
  • Pray Melee
    Rex hits with melee (stab) — Protect from Melee tanks him for the whole fight.
  • Kill with magic
    Rex tanks melee and ranged (255 defence bonus to each) but has just 10 magic defence and a magic level of 0 — magic obliterates him.
  • Stand under Rex for safety
    Standing on Rex's square forces him to attack melee only. Combined with Protect from Melee = 0 damage from Rex.
  • Food + prayer pots
    Sharks + Prayer pots / Super restores.
