These mods are pretty good when used together with EDFR. They are not required, but they enhance the End's other lacking features. They are highly recommended, but not required to use EDFR.

Attack order:

1. Force endermen to attack random player.
2. Summon end zombies.
3. Shoot fireballs that explode.
4. Force the dragon to perch. (Replaced with another fireball attack when dragon is Mad)

After the dragon reaches half-heath, she will become Mad. When she becomes Mad, she will respawn 3 end crystals and be able to use Mad attacks. She can only become Mad once, even if her health goes above half again.

Mad attacks (only used after the dragon reaches half health):

1. Teleport to random end crystal location.
2. Strike lightning on everyone (if you are moving, the lightning will appear where you were a second ago.)
3. Summon anvils 20 blocks above everyone (more visual flare planned)
4. Spawns miniboss (only one miniboss can exist at once, and only one miniboss can be spawned per fight, and the dragon will no longer move while miniboss is in existence, so you have to kill the miniboss)

The attacks are subject to change as I plan on adding more and changing some.
