Ancient Amuletor (HP)

This trophy requires you to use the gunner. You’ll need to get several kills with your normal attacks to unlock your skill. Once unlock either allow 10 enemies to amass around a single crystal or simply ensure there are 10 enemies that you can get to by teleporting to different towers then hit the button on your left controller and start firing as fast as you can. You have unlimited ammo for a short time so don’t worry about reloading. If done correctly you’ll have killed 10 or more enemies and the trophy will pop. I found 2-1 to be a good level for this but any level works.
