Saw the [Dual Zoren]'s high crit chance and damage and felt that it could really be capitalized on.

If you wanna spend a couple more Forma, you can swap out [Drifting Contact] for Primed [Rush]. This will make your combos not last as long, but they'll get higher faster.

Additionally, putting [Gladiator Resolve] and [Gladiator Aegis] on your Warframe will boost the set bonus further, making the combo counter more powerful.

If you've got the Focus, the Naramon school has the ability Power Spike, which makes the combo counter slowly decay instead of completely disappearing when the timer runs out. Naturally, this would be worthwhile to use.
