Pile driver, 2 songbirds and some other high impact you can carry

Open with charged pile driver, immediately unload all your cannons into it, slap another charged pile driver while it’s stunned

After that only go for pile driver when it’s stunned

I played with reverse joint, but i reckon quad would be the best, as you can just stay above it, outside its melee range.

If it pounces at you while you’re on the ground close to it, dive under it
