Capture, yes.

But do take note you can't capture elder dragons.

Yes, hunt you can either kill or capture. But the rewards are better for capturing and shorten the hunting time since you won't need to kill it.

During a capture you can ONLY capture it, not kill. Killing it will result in mission failure.

the tricky part is keeping the pukei alive and fighting both leshen and the jagrases.

use your flash pods, lifepowders and igni on the jagras ... try to keep one jagras alive or else leshen will keep spawning more of them.

You have to play defensive. Stunproof and health boost is a must. Speed eating is not necessary but will help at least so your hunter doesn't need time to heal. What weapon do you play? Always stay away from his front. Attack his side or back. Once you managed to make him flinched or stun, then attack his head. When not enraged, try to clutch onto him and shoot your slinger ammo for some face wall damages.

Oh, at least you got friends to help. Try solo like melah, lolol

Didn't buy PSN plus. Also I rather rely on myself than random strangers.

Does Blackveil Vaal Hazak will appear in Expedition if you have not unlocked it in the Assigned Quest (Main story)?
