Hydra

The hydra is a mega boss that can be found in the hydra's lair with 3 stages

stage 1: 3 headed hydra, dark purple and black, very slow, shoots fire, summons are dark tower and makes a red aura kind of like a hammer hit if you get too close

stage 2 : 2 headed hydra, yellow and orange, some what fast and shoots a lot more fire

stage 3 : 1 headed hydra, red, final stage and fast shoots fire summons dark spire and does a lot of damage to people with no or not good armor

Drops: Hydra Mask (rare), Dark Spellbook (common), Colossal Blade (common), Dragon Tooth (rare)

Bug: There is a bug where if you shoot the hydras flames you take damage because the bullet trails are counted as your hitbox so you take damage when you shoot at the flames. This works with pretty much any ranged weapon. To avoid this listen for when the hydra is about to shoot fire and stop shooting until the fire is gone.

TIPS: Use blackhole staff to get hydra away from you so you can heal. BEWARE it risky because what if hydra lands on you or hits you with its fire so keep moving while you summon blackhole. Also useful is to bring at least a quick potion to dodge fire attacks better. Try to use ranged weapons to stay away from they hydra

Tip 2: Use mountain dew or speed potion, your weapons will be Dark Spellbook (Dungeon Drop or Hydra Drop), and Ultimate Spellbook (You can use the True version, and the death, nacker, and omega death tome to deal more damage), and magic lamp (drop from Helios). Idea is to use magic lamp then use both spellbooks on the hydra up close, run away when he force field disappears keep running and avoiding the attacks until you can use your magic lamp again
