Raid TL;DR

• Drumbarka is a 2-phase boss with 2 armor types.
  • If you're doing EXT, just blast the kani. It's only 8M HP.
• Phase 1
  • Crab has 4 targetable parts: Face, hat, 2 claws.
    • Hat is red armor, takes less EX skill damage, but is not default target. Need focus target.
    • Face is blue armor, but has 50% DR on TOR and above. Attack claws instead whenever possible.
    • Claws are blue armor, and they are breakable. Will only be targetable for a short period after claw strike.
  • Crab bubble beams for massive damage. Bring red tank, keep alive or get team wiped.
  • Control panels exist to move platform via cleanse mechanics. Bring cleanse, game tells you what and when to target.
  • When hat and both shells break, you do more damage.
• Phase 2 (50% HP)
  • Crab has 2 targetable parts: Body and claws.
    • Body is blue armor, takes less EX skill damage, and charges up crane.
    • Claws are red armor, takes double red damage, but are not always available. Only targetable with EX skills.
  • Drum barrel
    • 1 debuff every 10s, plus another every crab spit. Does DoT dependent on debuff stacks.
    • Cleansing will boost damage for 35s. Also does small damage boost on crab per stack cleansed.
  • Cargo crane
    • Crane is charged by shooting body. After use, damage requirement doubles.
  • Counter state
    • After full ATG gauge (3 yellow boxes), crab gets a red HP bar for ~20s. Try to fill red HP bar, then use crane to do big damage. Just remember to not delay too long, also you don't need to hit the cap. Crane takes ~2.5s to swing.
    • Max threshold is 3M/6M/10M (INS/TOR/LUN). Doubles on second time.
