Tonbo

Early-Mastery polearm with long reach, Slash-weighted attacks, and a Madurai polarity.

Released Feb 18, 2015

Tonbo is an early-Mastery polearm with 3 m listed range, a large Slash share in normal attacks, and 25% status chance. Consider it for straightforward reach and status-focused melee use; its listed critical chance is only 5%, so critical-focused investment has less support from its base stats. It also has Blast slam damage in both regular and heavy modes.

Tonbo GUIDE

Understand Tonbo

Useful when…

  • Use normal attacks to take advantage of its Slash-heavy damage and 25% status chance.
  • Use the 3 m range for melee reach and slams for area damage.
  • Consider the built-in Madurai polarity when arranging mods.

How does it handle?

Tonbo's normal attack deals 184 listed damage: 138 Slash, 27.6 Puncture, and 18.4 Impact. It has 5% critical chance, a 2× multiplier, 25% status chance, and listed speed 1. The weapon has 3 m range, 0.6 follow-through, 55-degree blocking angle, and a 0.9-second heavy-attack wind-up.

What do the slam modes do?

A regular slam deals 368 Blast in an area, with falloff to 7 m and 50% reduction. A heavy slam deals 552 Blast in an area, with falloff to 8 m and 30% reduction. The separate heavy-attack damage listing is 1,104. Both slam modes list 10% status chance, so the normal attack's 25% status chance should not be carried over to them.

What investment makes sense?

Tonbo requires Mastery Rank 3 and has a rank cap of 30. Its low listed critical chance makes a status-oriented direction a more natural consideration from the base stats: normal attacks have 25% status chance and are predominantly Slash. It comes with a Madurai polarity. The recipe lists two Control Modules, 2,000 Ferrite, 100 Oxium, and 800 Plastids; crafting time is 43,200 seconds (12 hours).

How do alternatives differ?

Dakra Prime is a sword with 36% listed critical chance and a 2.4× multiplier, rather than a long-reach polearm. Anku is a scythe, while Ankyros is a fist weapon whose description emphasizes close-quarters combat and speed.

Limitations and tradeoffs

  • Very low listed critical chance; normal attacks instead have 25% status chance and Slash-heavy damage.
  • The heavy-attack wind-up is 0.9 seconds.
  • Slam attacks have 10% listed status chance, unlike the normal attack's 25%.

Common mistakes to avoid

  • Do not apply the normal attack's 25% status chance to either slam mode.
  • Do not confuse the 1,104 heavy-attack listing with the 552 heavy-slam figure.
  • Do not build around high base critical chance; the listed value is 5%.
