Phase 1 - Activating the Boss
Before starting: Before starting: it's important for everyone, except the tank, to have their bag slots filled. You don't want someone to accidentally take a tome, forcing them to charge it. If that happens, buff them.
The tank needs to take books from the obelisks and charge them by absorbing the explosion from the orb dropped by the black viper when it dies, then, return it to the obelisk. You need to have an empty slot in your bag to pick up a book. To pick up a book, you just need to get close to an obelisk (it will be picked up automatically).
Orbs: During the book phase, the hydra will throw an orb on a random spot of the arena every 5 seconds. 3 seconds after landing, the orb will explode spreading 12 pellets in a circle. These pellets fly through the whole arena and deal damage on contact. In VX mode, this will continue throughout the entire fight.
