Axe: After a set number of Wild Swings, follow up with a Heavy Slam to activate Power Axe Mode. While active, your axe attacks will cause monsters to stagger more easily.
You can use your clutch claw during an Element Discharge. Connect with a large monster to grab ahold of it. The claw attack will also increase phial output, making it easier to go into an Amped State.
While in an Amped State, you can follow up a clutch claw grapple with a Zero Sum Discharge. Use your claw to get close, then unleash the pain.
Slinger bursts are possible after a number of axe attacks. You can also follow one up with an Axe: Morph Sweep.
