Aetherium

What is Aetherium?

Aetherium is a mod for Risk of Rain 2 that adds in a few items of varying tiers. Most of the item ideas listed were sourced from the ideas channel on the official discord, and as such the ones that were I will list the person that came up with the idea next to them.

The mod so far has the following items implemented:

• Feathered Plume (Original idea by Ajarl, altered a tiny bit)
  • White Rarity - 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.)

• Shielding Core (Original idea by NepNep)
  • Green Rarity - You gain 10 (+5 per stack) armor while BLUE shields are active. The first stack of this item will grant 4% of your max health as shield on pickup.

• Shark Teeth (Original idea by FancyFrenc)
  • Green Rarity - 25% of damage taken (+25% per stack, hyperbolically) is distributed to you over 5 seconds as bleed damage.

• Blood Soaked Shield (Original Idea by Kaboose, altered quite a fair bit)
  • Green Rarity - 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.

• Blaster Sword (Original idea by Bord, altered a bit by me.)
  • Red Rarity - 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.
  • Known Issues? - MUL-T's nailgun fires an absurd amount of swords. They aren't super powerful (as they're based on MUL-T's base damage), but they are a bit spammy on him.)

• Inspiring Drone (Original Idea by Kaboose "Aftermarket Spare Parts", altered a ton from that.)
  • Red Rarity - When a bot is purchased, it gains a 50% boost to each of its stats based on yours (+50% per stack, linearly).
    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).
  • Big Credits To - Chen of the Chen's Classic Items and Chen's Gradius mods for putting a ton of work in to improve the Inspiring Drone's code as of 0.3.2.

• Accursed Potion (Original idea by Shadokuro, slightly modified by me.)
  • Lunar Rarity - 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.

• Alien Magnet (Original Idea, if you call a vacuum original)
  • Lunar Rarity - 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.)

• Weighted Anklet (Original Idea)
  • Lunar Rarity - Gain a 25% reduction to knockback from attacks (+25% per stack (up to 100%) linearly). Lose 10% move speed (+10% per stack (up to 40%) linearly).

• Unstable Design (Original idea by Spooky Boogie, altered a bit to improve)
  • Lunar Rarity - "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."

• Heart of the Void (Original idea by Hyperion_21, altered a bit to improve)
  • Lunar Rarity - "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.
  • Known Issues - With PlayableVoidcrab mod, all runs (including the current) after the Voidcrab has died will cause every Voidcrab explosion to occur instantly when triggered, including this. This is fixed by restarting.

• Jar of Reshaping (Original idea)
  • Equipment - 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.

Upcoming

• Version 1.0.0 will include a new survivor, we're building up to that.

• ItemStatsMod integration soon, possibly 0.4.3.

• The Key of Solomon idea is being brainstormed, but will still likely focus on stealing skills from enemies. However, those skills will likely be custom made by me, who knows.

• Weighted Anklet will be reworked soon to be more desirable. How I'll do that? I'll have to think on it.

• Make kills by the Lunar Chimera give half XP/Half Gold to the Unstable Design wielder. Make its spawn behavior configurable between individual per player or similar to halcyon seed.

• Will be adding more custom VFX/SFX to the Jar of Reshaping now that I'm more familiar with effect networking.

Changelog

[0.7.1]

• Buff Brazier prices are fixed
• Added Mercenary Expose debuff buff brazier, it is kinda cool you have to admit, same price as Brainstalks one as it could be OP

[0.7.0]

• Hopefully fixed Voidheart overlay issues, do let me know if I couldn't

• Now maintained by Phreel
• CHANGELOG.md
• Initial fixes for SotS (namely Alien Magnet, Planula x Voidheart cheese is back but soon will be patched)
• Artifact of the Tyrant now supports False Son

[0.6.8]

• Hopoo Games is at fault for this patch version. Aaaaaaaaaaaaaaaaa!!! Fixes the Weighted Anklet Limiter Release not having deprecatedTier set, but instead having tier set which causes it to show up in regular item pools.

[0.6.7]

• Lots of bugfixes to make the mod compatible post-SOTV. Thanks to Bubbet, Time, and everyone else that contributed towards fixing Aetherium up.
• New Heart of the Void explosion VFX. Sound is coming next update for it.
• Modified Artifact of the Tyrant to affect all route-ending bosses instead of just Mithrix.

[0.6.6]

• Fixed NRE in Buff Brazier that happened if you completed a teleporter event with an orb, but didn't have any next teleporter event (woops!).
• Reduced default duration of Shark Teeth's damage spread to 2 seconds from 5, should synergize better with certain items and not screw up others as much.
• Restored the missing Heart of the Void cell shader, didn't realize it was missing.
• Fixed texture artefacts arising from using point sampling and normal compression (to save on mod size), but sadly we're gonna be 50mb or more for the moment.

[0.6.4]

• Adds Bell Totem, an equipment/interactable hybrid that spawns an interactable bell totem that throws enemies back and stuns them. It also triggers any On Shrine Use effects.
• Adds an Entity State blacklist for Sanguine Elites that prevents the dash from interrupting specific attacks. Currently, it prevents the dash from cancelling Mithrix's item stealing and fist slam.

• Hides Limiter Release item icon. I couldn't figure out an icon for the moment for it, and it has a buff anyway that shows you the count of Limiter Releases you have.

[0.6.3]

• Adds Sanguine Elites. Elite buff icon was done by FOG, display model done by Ragon. The elite type grants abilities similar to the regular imps, including bleed on hit and a special dash ability. Players get invulnerability during the dash state but have a mandatory cooldown period between uses of the dash. AIs get the ability to chain dash if their enemy is too far away, but if they dash too often in too short of a period they get stunned.
• Added Zenith Accelerator, a lunar that decreases your attack speed initially but you gain it back and then some with continuous hits. If it's too powerful, I'm going to add another downside. We'll see.
• Fixed memory leak issue from using the tracer from Mul-T's nail. It doesn't clean up its smoke.
• Added a temporary visual effect to Jar of Reshaping's opening.

[0.6.2]

• Adds Artifact of the Journey. When enabled, stages will be chosen randomly. The dream seers in the bazaar will also be randomized. After every 5 (or stages per loop) amount of stages, a Primordial Teleporter will be placed.
• Fixed Heart of the Void's overlay pulling from the wrong material. You can no longer be thick and veiny after reviving by it.
• Fixed a rare culture specific issue regarding using "ToLower" to do a dictionary lookup. It's now culture invariant.

[0.6.1]

• Fixed odd infinicombo Nail Bombing. It can no longer proc from a hit with 0 proc coefficient.
• Fixed readme.
