The Mech

The Mech is a late Pre-Hardmode boss which is made to prepare the player against the Mechanical Bosses. It is difficult unless the player is farming with Hard Mode/War Mode items or the players practices and plans carefully for the fight. It has two stages of the fight.

Phrase 1

 * Phase 1 Health: 4800 (5400 in Expert Mode)
 * Phase 1 Defence: 60 (80 in Expert Mode)
 * Phase 1 Damage (Gun): 40 (50 in Expert Mode)
 * Phase 1 Damage (Hammer): 80 (100 in Expert Mode)
 * Phase 1 Damage (Body): 60 (75 in Expert Mode)

Phrase 2

 * Phase 2 Health: 4000 (5000 In expert Mode)
 * Phase 2 Defence: 65
 * Phase 2 Damage (Guns): 80 (120 in Expert Mode)
 * Phase 2 Damage (Body): 120 (200 in Expert Mode)

Phase 1
The Mech has legs and stays on the ground (With the occasional jump). He will try to shoot the player and get just in range to use the hammer. He will walk around constantly, this meaning mobility and height is critical. The Mech can jump onto platforms however.

Phase 2
Once taken down to 0, He would regain 4000 health and his legs disappear. He would then become some kind of helicopter with arms that cannot be landed. He would grow two guns on his sides which fire constantly, he will also always be above the player. In order to beat him, the player must take him down back to zero.

After Math
Once lowered back to zero, the following happens:
 * More Voodoo Demons spawn.
 * The Spreading of the Corruption/Crimson speed up a little bit.
 * Unless Skeletron is defeated, The Old Man at the dungeon will instead say: "You may enter, you are very worthy." Which means the player can enter the Dungeon without facing the Dungeon Guardian.
