This datapack adds an Entity 303 boss battle to your minecraft world.
Create an altar using 4x Cultist banners and 1x Lodestone. Drop a totem of undying on top of the lodestone to summon Entity 303. You can get your hands on cultist banners by killing "303 Cultists" that spawn in ice biomes.

Follow the instructions in this video to build the altar: youtu.be/F4U7Nlh0Pw8



Note: Entity 303 is harder to defeat than the ender dragon. You will take a lot of direct damage in this battle so use the best gear you can get your hands on. Totem of undying and shields can be very useful. Long range weapons are recommended.

When Entity 303 spawns he will create a small explosion. The first thing he will do is to either scour the area or immedeately attack you with highly explosive fireballs. Dodge his fireballs with all you've got because getting hit by only one can be lethal.

Dodge all fireballs that Entity 303 fires at you. You can either run away from them or deflect them. Deflecting fireballs att Entity 303 won't hurt him.

Sometimes Entity 303 might fly high up in the air and then fall down to the ground with a tnt. Use this opportunity to fire arrows at him when he lands and is close to you.

When Entity 303 has lost half of his HP he will sometimes teleport himself to you. Be very careful when this happens because he will summon a tnt at your location and might at the same time also shoot a fireball at you.



303 Shard is found in the chest that spawns when you kill Entity 303. 303 shard blesses you with 6 extra HP (3 hearts) when it is in your offhand slot.

Entity 303 has no minions, less health, but does more damage, but I think Herobrine is harder
