Fragor Prime

Pure heavy-slam Fragor — Corrupt Charge and Seismic Wave fatten ground hits while Primed Fever Strike keeps raw toxin so shields do not gate the first anvil drop.

Steel Path slam variant that trades Gladiator Might for Primed Smite Grineer — multiplicative faction damage on toxin slams when armored Grineer stop dying to raw Anvil Drop.
