Using your elytra and fireworks you will fight all others teams but you all have one heart so even if you are hard to hit one hit and your dead but there is no count system this is for ou to count how someone wins.
There are two arenas at the moment i started the third one but i didn't had any ideas on how to decorate it.
Also this map uses a custom resource pack made my sixfootblue the ItemBound v1.4 here is the link.
You can still play this map with out this resource pack but with this you have multiple choices on items to equip your self for the battle.
