Why this Grom build works

A C-tier artillery like Grom strongest build in 2026 is the "Foot Patrol" Star Power together with the "Watchtower" Gadget. "Foot Patrol" is the pick that turns Grom's baseline into a real threat — it scales with the way a artillery wants to trade, and the numbers back it up (51.4% win rate, 4.9% pick rate). "Watchtower" adds the exact utility the kit is missing: burst, reposition or lockdown depending on the situation, and it converts neutral fights into won trades when timed with your Super. For gears we lock in Damage as the primary because it compounds with the Star Power the most on Grom specifically — swap the secondary to Shield on open maps or Damage on close-range brawls.

Grom Gadgets

WatchtowerBest pick

Grom ejects a Watchtower from his Grom Bomb that gives all allies sight into bushes over a large area. The watchtower slowly loses health over time.

Radio Check

Grom's next attack throws x Buds in rapid succession.

Grom Star Powers

Foot PatrolBest pick

When Grom's Super is fully charged, he gains +% faster movement speed!

X-Factor

The split from Grom's main attack deals up to +x% extra damage at max distance.

Situational alternatives

If the map favours long-range enemies, swap "Watchtower" for a repositioning Gadget when available; in Brawl Ball, Shield gears keep Grom alive long enough to land the Super, while in Heist and Bounty the Damage and Speed gears squeeze much more value out of "Foot Patrol". The real rule is simple: adapt the build to how opponents try to punish your artillery role, not the other way around.
