Salutations my fellow intellectuals and welcome to this guide.
I'll make it short.
If you are a new player you wont know about the OP the trick in here. Many guides will tell about the intended way to play the game and progress, but neglect to tell you the most optimal way to play. That is what I'm here to do.

screw normal progression, im here to show you the fastest way to progress, so you can get chaos arcana sooner and screw around with more funny build ideas.

So you want to level up? Wanna go further in the chaos trials faster? Wanna start the game with 95%+ move speed and 100% dash evasion chances to run donuts around master sura? Perfect. For you, I have the BIG FUNNY.

The BIG FUNNY is a glitch that allows you to bring more than one relic from your chest into the chaos trials, allowing you to start with incredibly cursed and custom made builds out of the gate.

To perform the BIG FUNNY, go to the place you spawn when you first join. Move to the leftmost room and talk to the mirror. Say yes to both of his questions, and proceed to the tutorial flashback. Complete the tutorial and it will teleport you back to spawn.

This is where the fun starts.

Drop the relic you are currently holding on the floor by opening your inventory and pressing the drop button (F on keyboard and mouse). You cannot drop pre-game in any other part of the map in this game. Only here. Speak to the chest and grab another relic, a different one as the one you dropped. Drop that one aswell. Continue until you have dropped a satisfactory amount of relics. Pick up all of your relics, and without purchasing anything or opening any menus, proceed to the chaos trials. Please note you cannot carry more than ten relics into the trials. If any of the relics you plan to include in your build happen to be non droppable, just have them be the last purchased relic in your pile and do not drop them, leave them in your inventory to be joined with the rest.

Optional: If you have completed the game atleast once, you may also purchase a cursed relic from Nox in the upper left hand corner of the play area. However, to not loose all of your relics apon purchase, drop all of your droppable relics on the ground infront of the shop before you buy anything. From there, pick them up, and continue to the chaos trials, entering as a terrifying demigod on the very first level.

Already I'm sure you can see the impact this glitch could potentially have in a run, even as a new player. For this reason, I would suggest buying relics at a rate comparable or higher than your robe and ability purchases, so you can exploit this to it's fullest potential as soon as possible.

One of my favorite combinations that works for (relatively) early game is this:

Dark Katana: Triples your crit chance
Critical Monocle: 8%+ crit chance
Claws of Tomo: Increases crit chance by 5% and enhances your basic arcana.
Auditor's Talisman: Increases crit chance by 20% at low health
Assasin's Blade: Increases crit damage by 50%
Vampire's Eyeglasses: Heal yourself whenever you land a crit (WHICH IS VERY OFTEN)

This makes crits OP allowing things like the basic spark blast with the normal berserk or the drill to suddenly become melting beams of death.

You can add onto this with items like the Dice of Nemesis or the Covert Opps mask and evasion items. Im not going to mark down every one of the potential options for this build, mainly because I dont know them all but also because alot of the fun is finding new synergies.

But we must go further. What is the one major limitation of this technique? The limit of only ten max relic slots. However, this can be subverted somewhat with secret combination relics. My personal favorite application of this is combining the elemental painter items (fiery paintbrush, electrifying smock, sturdy wooden easel, breezy gray canvas, watercolor palette), all of which have very good boosts and all of which can be combined into one item and only take up one slot. However, they are only effective if you have all/most of the relics unlocked for each element.

You can move at supersonic speeds by combining the rainbow tail, equestricap, and mercury's sandals to go super fast.

There are many MANY more combinations you can build including an infinite coin glitch, one hit punch ability, and even more optimizations to the speed build, but i'll leave those to you (hint: watch A Raccoon on youtube with the links below)

anyway that'll be wraps for me. Hopefully this has helped new players get their first win and chaos arcana to speed-run or help older players have more fun with funny silly goofy builds.

As always, have a merry birthday and a happy Christmas, this has been

the one and only moss :D
