Gigantic Green Slime

The Gigantic Green Slime is a pre-hardmode boss that has a 1/10 chance of spawning during the Slime Rain event after the Eye Of Cthulhu has been defeated, but can also be summoned naturally by using the Possesed Gel anytime of the day.

It has 3400 Health, 5600 in Expert Mode, 15 defense, 20 in Expert Mode, 80 body damage, 150 in Expert Mode.

Phase 1
The Boss will behave similarly to King Slime, jumping at the player, summoning green slimes when damaged, but sometimes it will "throw" slimes at the player.

When it reaches 1700/2800 health, it reaches it's second phase.

Phase 2
Has all attacks from previous phases.

Now, sometimes when landing, will release a bunch of slow moving lasers in 8 directions, that have very high damage, plus inflict the slowness debuff.

Will jump higher and faster.

Tips

 * it's recommended to build a long platform, along with some blocks to defend yourself from the slime throwing and laser attacks, as they don't penetrate through blocks.
 * Due to it's high body contact damage, ironskin plus swiftness potions could sometimes be a life saver.

Lore
Once, the world has been infected with a dark essence, evolving, mutating anything that stands in it's way, even the strongest ones, weak ones, it doesn't matter. A green slime was infected with it. The dark essence entered into it's body, rapidly reproducing itself making the slime bigger and stronger, eventually, it turned into a giant slime beast with no mercy to challengers. It had the power to reproduce itself with a little cost of it's power. The Slime starting to reproduce, populating the world with slimes, each one jumping to world evils, slowly became a part of them, being forced to stay in their particular biome, commanded to attack anything that dared to face the gigantic slime.
