Results

DPS vs Abyssal Sire

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
  • Phase 1: Pray Magic, kill respiratory systems
    Stage 1 is two 'tentacles' that breathe poison clouds. Pray Magic, hit them with Tbow / crush, watch your minimap for poison clouds (they move 1 tile per second).
  • Phase 2: Stun him
    When Sire wakes, throw your stun item (a Bandos godsword spec / Dragon claw spec / DWH spec) to stun and double damage during phase. Without stun, phase 2 is much slower.
  • Phase 3: Kill spawns or get stuck
    Sire spawns 'baby' Sires that aggro you. They die in 1-2 hits. If not killed they pile up and corner you.
  • Watch the poison cloud minimap
    Clouds spawn periodically through all 4 phases. They deal +24 per tick — fatal if you're standing in one without prayer.
  • Food + prayer pots + anti-poison
    Sara brews + Super restores + Anti-venom+.
