Notes[edit | edit source]

  • Performing a Slam Attack will emit arcs of Electricity b.png Electricity at targets within 8.5m that deal damage with a guaranteed chance to proc. Unlike a standard ​​​electrical proc this arc does not chain to secondary targets and its damage is unaffected by elemental damage mods. Mod TT 20px.pngSeismic Wave increases the damage of the arcs. Arc range is not affected by range mods (e.g. Mod TT 20px.pngReach & Mod TT 20px.pngPrimed Reach). Mod TT 20px.pngDispatch Overdrive and Mod TT 20px.pngHealing Return both work with arcs. This ability is separate from and in addition to the normal Slam Attack range, damage, and status chance.
  • Damage caused by the Ohma (including damage over time effects from status effects) will cause an arc of lightning to emit from the Ohma striking the target, this arc has no additional effects and deals no damage.

Tips[edit | edit source]

Trivia[edit | edit source]
