The Thunder King

Zentaro (Zenitsu)

Zentaro drops the Thunder Katana, the Thunder Haori and Flaming Thunder God, Thunder's last move.

Some players cannot find him: he stands on open foggy grass by a big tree, just north of the Hidden Mist shrine.

Foggy grass north of Hidden Mist

Open foggy grass by a big tree and a rock, north of the Hidden Mist shrine and just east of Obari.

  1. Teleport to the Hidden Mist shrine and walk north.
  2. Or kill Obari first and ride east for about ten seconds.
  3. His bar appears by the tree; the full route with pictures is on the boss locations page.

His scroll line read 5% at launch. The v.09 patch raised every boss skill drop, and the other seven Hashira now read 10%, so his is likely 10% too; the table keeps his launch figure until his bar confirms it.

A loop with Obari

  • 3,000 health alone, 1,000 more for each extra player.
  • Each kill costs 120 Reputation.
  • Obari is a ten-second ride west, so the two make one loop; together they cost 240 Reputation a round.
  • Thunder itself was weakened in v.09 and reportedly strengthened again in V0.110; the Thunder page has where it stands.

Kintsugi Haori and dry streaks

Does Zentaro drop the Kintsugi Haori?
Two players say so, but it is not on his bar. If it comes from him, it would be from his chest; that is not confirmed.
30 kills and no katana. Is it bugged?
At 5%, about one player in five goes 30 kills without it. It is bad luck more often than a bug.
