Tyl Regor's custom axe and shield are how he likes to eliminate 'frustrations'.

The Ack and Brunt is an axe & shield set used by Tyl Regor that boasts a high critical hit chance in exchange for a low attack speed. It also has the unique ability to absorb elemental attacks on block to empower the weapon's next attack.

Characteristics[edit | edit source]

This weapon deals primarily DmgSlashSmall64.pngSlash damage.

Notes[edit | edit source]

  • Blocking elemental damage attacks creates a stack that increases the damage of the next attack by 17.5% stacks. The effect can stack up to 4 times before being consumed, increasing the damage up to 70%.
  • The damage bonus increases additively with elemental mods, which can also combine with elemental mods from the weapon to became a combined elements. For example, if your Ack & Brunt is modded with DmgElectricitySmall64.pngElectricity damage (e.g. Mod TT 20px.pngShocking Touch), blocking DmgFireSmall64.pngHeat damage from a Flameblade's GrnDualFireAxe.pngTwin Basolk will combine it into DmgRadiationSmall64.pngRadiation damage on the next attack.
  • Elemental damage taken by nearby allies via Mod TT 20px.pngElectromagnetic Shielding can be converted to stacks.

Tips[edit | edit source]

  • The Ack & Brunt's high critical hit chance makes it ideal for Mod TT 20px.pngBerserker, which can be used to compensate for its slow attack speed.
    • (Mod TT 20px.pngPrimed) Mod TT 20px.pngFury can be used to further increase the attack speed.
    • Mod TT 20px.pngFinal Harbinger can offset the Ack & Brunt's low attack speed with its quick combos.
  • Using the Ack & Brunt with Mod TT 20px.pngFinal Harbinger, Mod TT 20px.pngBlood Rush and/or Gladiator Mods allows players to quickly gather hits for the Combo Counter, rapidly boosting the Ack & Brunt's critical chance.
  • Absorbing enemy attacks allows players to almost double the amount of damage they can deal.
    • This is useful when focusing on taking down heavy units in a crowd.
    • Do note however that stacks are expended if an enemy melee attack is parried.
  • (Corrupted) Bombard rockets can add up to two stacks of elemental damage, allowing players to collect stacks faster.

Trivia[edit | edit source]

  • This is the weapon of choice for Tyl Regor following Update 17.0, though instead of holding the weapon, Tyl Regor is able to attach the axe and shield to the ends of his cybernetic limbs in place of his GrnArchHand.pngKnux hands. Regor, however, explicitly refers to Ack as a gavel.
  • Tyl Regor uses a different design for the shield, as it is normally part of his helmet/headdress (or perhaps vice-versa). The Tenno version presumably adapts the shield to collapse so that it does not take up as much room when stowed.
  • The text on the inner part of the shield translates to "Meat Protector".
