Spider King

Who this boi?
Spider King is the hardest mob to beat in game currently because it is a boss that makes sense. It has a whopping 5.5M HP(Increases by 1M per player) and does according to my experience around 10k dmg per hit and either insta kill you or fling you sky high with webs. The more players the higher the spider's hp.

Goodies
Its EXP drop is a bit disappointing (500 xp) but it can drop the stuff below:

Sewer Key (75% chance)

Spider Fang Potion (10% chance)

Spider Crown (10% chance)

Arachnid's Pickaxe (3% chance)

Arachnid's Axe (3% chance)

Spider King Mount (0.5% chance)

Arachnid's Edge (5% chance)

King's Blade (1% chance)

Extra info
Allegedly, solo beating the spider king unlocks the advanced blacksmith in the Main Village, with "Developer weapons", soloing means it practically can't be glitched, and due to it seemingly following a pattern, to my knowledge this is nigh impossible with the current lack of more powerful armor and pre-spider king tools.

Most weapon drops and items are locked to rank 100, don't get too excited if you're a dungeon newcomer that got into a group that ended up killing the spider king and got a weapon/item. (The only unlocked items (to my knowledge) are the Arachnids axe And arachnids Pickaxe, both have a level requirement of 0, see below)

Arachnids pickaxe and Arachnids axe are both currently bugged to my knowledge, and cannot be even swung/used, which was a large letdown for many players that grinded for them.

In combat/Tips
Due to the lack of health items relevant to the players power at this point in the game, they're practically useless, so going for more Health skill points instead of damage is mostly recommended for the scaling regeneration, you should also at least have Phiodide armor if you're going in with smaller groups, duos, or trios.

The spider king can easily be glitched with two or more people, the more people there are the easier it is, this is accomplished via having someone it's consistently targets get killed, or have more then one person killed, this should bug out it's AI, and leave it unable to attack, if this happens, some awareness should be present, stay away from the middle, as it can still use its knockback orb attack, and the purple acid will rise during this, a cocky player or two can easily die due to this.

The spider-king's mandible bite attack cannot be dodged. It doesn't matter how far away you are, it will turn on it's ESP minecraft kill aura and won't hesitate to hit you from across the 20th colony of england, in short the spider king is a sore loser that bought 15$ hacks. (this makes me unreasonably angry in game)

During the spider web attack, its suggested to use a mount (As you should for the entire fight), and stay aware, the projectiles blast radiuses are small, however a direct hit will often cause you to glitch out and noclip into the purple acid, instead of having conventional knockback, the mesh of the explosion effect is in fact solid, therefore it can fling you at up to mach 3 speeds.

On the outer and inner platforms when the purple acid rises, be aware, due to the game being strictly in R15, your feet can clip through the ground and hit it, mounts are further recommended here to raise your hitbox, so you're not hit by bad game design and a wave of disappointment.

The black knockback orb that occasionally appears in the center can be easily dodged, with or without a mount you can simply run against it and hug it for dear life, and you often won't fall off, this can be useful if you have high ping and glitchy jumping, it can be used to avoid having to jump over the chasm of purple acid. (More of a puddle.)

One of the things cocky players often die to is this awful mechanic where if you stand in the middle when the spider king reappears, you will instantly die. This can take a lot of players by surprise, and same with rushers that just try to do as much damage as possible.

On top of this buggy mess of a semi-enjoyable boss at the best, It's hitbox is GOD AWFUL. Roughly 65-75% of the hits you throw will pass through it due to the spider king's 2001 PC that sustains a constant 3283 ping.
