Want to make your own pvp arenas? How about this for an idea;
You use a golden axe or something like that and choose an area like if you to claim an area(right clicking a corner than the opposite corner), then you create spawn places by left clicking with said item on the ground. in these areas, deaths respawn you in the spawn areas, and you keep your loot and take no durability.
It should cost more than claim blocks, as these areas could be safe havens, as deaths are harmless
You cant make these areas in claimed land, unless its yours, and it should not be a grief protection.
idk if it should be a rank perk, but if so, it should be vip/elite, as those are more resourceful ranks.
