Achlys (Goddess of Misery)

A new boss type in the underworld/nether or another dimension. she radiates Weakness, Nausea, Slowness and jump boost. if you get to close to her she inflicts STRONG damage, the damage gets stronger the closer you get to her. she has no weapons, and she doesn't shoot projectiles. she starts damaging you through an aura effect and the only way to kill her is by using projectile weapons or potions. You can minimize her aura buffs and damage by placing different assortment of flowers (not wither rose) in your path. You can NOT kill her with a sword, cause if u get within 4 BLOCKS of her she will kill u instantly! If you encounter her in game she will spawn with a damage radius of 29 Blocks, you can also spawn her in with certain items - the more wither roses you place around where you are going to summon her the longer her damage radius will be (only up to 55 blocks) MINIMUM Damage Radius 25 Blocks, MAXIMUM Damage Radius 55 Blocks. She will be challenging as she will not be hurt by Melee Weapons, Swords, Axes etc!

I don't mind how she looks or what people use to summon her, but please keep as many of these aspects in as possible...

Thanks ;)
