	Feathered Plume	Gain a temporary 7% speed boost upon taking damage that stacks 3 times for 5 seconds. (+3 stacks and +0.5 second duration per additional Feathered Plume.)	White	Ajarl
	Nail Bomb	Attacks that deal 120% damage or more release a shrapnel grenade that explodes for 20x30% of your damage (+50% more per stack). Enemies hit that launched a nail bomb are granted 2 second(s) of immunity to the effect.	White	Zeddy
	Blood Soaked Shield	Killing an enemy restores 10% max shield (+10% per stack hyperbolically.) The first of the stack of this item will grant 8% of your max health as shield on pickup.	Green	Kaboose
	Engineers Toolbelt	You have a 20% chance (+20% hyperbolically up to a maximum of 100% chance) to duplicate drones and turrets on purchase. Additionally, you have a 10% chance (+10% hyperbolically up to a maximum of 100% chance) to revive drones and turrets when they die.	Green	Insane (originally) Me (Modified)
	Shark Teeth	25% of damage taken (+25% per stack hyperbolically) is distributed to you over 5 seconds as bleed damage.	Green	FancyFrenc
	Shielding Core	You gain 15 (+10 per stack) armor while BLUE shields are active. The first stack of this item will grant 8% of your max health as shield on pickup.	Green	NepNep
	Blaster Sword	At full health, most attacks will fire out a sword beam that has 200% of your damage (+50% per stack) when it explodes after having impaled an enemy for a short duration.	Red	Bord
	Inspiring Drone	Any bots you own gain a 50% boost to each of its stats based on yours (+50% per stack). Some bots gain more ammo for their attacks based on the bonus to their attack speed, and have their ammo replenished twice as fast per additional Inspiring Drone. Finally, if an inspired bot is too far away from you, it is teleported to you after a delay (40 seconds for Turrets, 30 seconds for Drones).	Red	Kaboose (original) Me (modification)
	Witches Ring	Hits that deal 500% damage or more will trigger On Kill effects. Upon success, the target hit is granted immunity to this effect for 10 seconds (-10% duration per stack, hyperbolically.)	Red	Me

Icon	Equipment	Description	Type	Original Idea by
	Bell Totem	On use, spawn an interactable bell totem at the chosen position. When activated, trigger a shockwave with a radius of 25m that stuns and sends enemies flying away from it. Additionally, any On Shrine Use effects will be activated. 2 second(s) between equipment uses, 1 second(s) between totem activations, and only one totem can be spawned per activator.	Normal	Ragon, modified slightly by me
	Jar of Reshaping	On activation, absorb projectiles in a 20m radius for 3 second(s). Upon success, fire all of the projectiles out of the jar upon next activation. The damage traits of each projectiles fired from the jar depends on the bullets you absorbed. After all the projectiles have been fired from the jar, it will need to cool down.	Normal	Me

Icon	Name	Description	Type	Original Idea by
	Accursed Potion	Every 30 seconds (reduced by 25% per stack) you are forced to drink a strange potion, sharing its effects with enemies in a 20m radius (+5m per stack) around you. Max: 8 buffs or debuffs can be applied at any time.	Lunar Item	Shadokuro
	Alien Magnet	Enemies hit by your attacks will be pulled towards you, starting at 6x force (+1 force multiplier, up to 10x total force. The effect is more noticeable on higher health enemies.	Lunar Item	Me
	Heart of the Void	On death, cause a void implosion with a radius of 15m (+7.5m per stack) that revives you if an enemy is killed by it BUT at 30% health (+5% per stack, max 99%) or lower, all kinds of healing are converted to damage.	Lunar Item	Hyperion_21
	Unstable Design	Every 30 seconds you are compelled to create a very 'FRIENDLY' Lunar Chimera, if one of your creations does not already exist. It has a 400% base damage boost (+100% per stack), a 10% base HP boost (+10% per stack), a 300% base attack speed boost, and finally a 24% base movement speed boost (+24% per stack). This monstrosity can level up from kills.	Lunar Item	SpookyBoogie
	Weighted Anklet	A collection of weights will slow your attack speed by 10% (to a minimum of 10% total) and your movement speed by 10% (to a minimum of 10% total). If you find a way to remove them, you are granted 0.25 attack speed flat scaling, 1 movement speed flat scaling, and 5% damage per removal. Additionally, removing an anklet grants you a stack of Limiter Release Dodge. Dodge will allow you to dodge one overlap, or blast attack before depleting. Once all stacks of dodge are depleted, they will need to recharge (10 seconds for the first stack, 5 seconds per each additional stack) before fully replenishing.	Lunar Item	Me
	Zenith Accelerator	Hitting enemies grants you a temporary attack speed buff that increases attack speed by 10% per buff stack linearly up to 300% (+100% per item stack linearly), but you lose up to 50% attack speed (+50% per item stack exponentially) the closer you are to 0 stacks of the buff.	Lunar Item	Ragon

Icon	Artifact	Description	Original Idea by
	Artifact of Leonids	After every 60 seconds a meteor shower will occur that contains 6 wave(s) of meteors.	Bord
	Artifact of Progression	Most enemies will evolve into stronger versions of themselves after a duration.	Chen, Me
	Artifact of Regression	If a monster is in an evolved form, it will split into a group of its lesser form when it dies.	Me
	Artifact of the Journey	Most stages will be randomly picked. After a certain amount, a primordial teleporter will be placed.	Tons of People, Bord
	Artifact of the Nightmare	Non-boss enemies are granted 1-4 of the Lunar Heresy items when they spawn.	Inspired by Hyperion_21
	Artifact of the Tyrant	Any time a route-ending boss spawns they will be given 1 random elite modifier.	Me

Buff Icon	Icon	Elite Equipment	Description	Modifier	Original Idea by
		Bloody Fealty	On use, teleport dash up to 10m in the direction you're going and gain slight invulnerability during the dash. Additionally, all of your attacks now cause bleeding.	Sanguine	Ragon, modified slightly by me.

Known Bugs

• Heart of the Void's new VFX has no sound.

• Inspiring Drone is incompatible with AllyNames mod
