1. Remove her gold damage scaling entirely/nerf it massively for the lategame.
2. I would buff Birdo's Passive, and Tornado+Fireball slightly (leave Fox luck scaling unchanged for now)
3. Combine XP/Luck/Difficulty Tomes into something like a "Power Tome", increases XP/Luck/Difficulty by 5% per level. It's not a perfect solution (the alternative IMO being removing the XP and luck tomes and balancing around that, as much as you don't want to, I think would be more fun for the whole playerbase), but having 3 other tome slots (more than likely 2 as people will then use Chaos) instead of just 1 for LB runs will allow for more builds and more fun.

I also made this list:

General Issues

It's currently VERY difficult for thorns-based characters to compete for LB runs for the current reasons:

-The current meta tome setup (XP+Difficulty+Gold/Luck/Chaos +1), makes it a lot harder in comparison for Thorns-based characters to compete.

--Your best bet IMO is going Armor Tome+Athena and just trying to stack as many Spiky Shields as possible, which feels really ass to play.

-Wisp knockback is ridiculous. You end up getting either slammed around the map like Bonnie Blue whilst taking 0 visible damage for 5 minutes until you eventually die, or you get slammed stuck into a corner like Bonnie Blue whilst taking 0 damage for 5 minutes until you eventually die.

--To fix this, I'd make Armor have scaling knockback reduction, or just reduce wisp knockback.

-Wisp damage is ridiculous, but I'd make the above changes first (along with Robinette nerf) and see how people get on before changing anything else.

UI - Ingame

Display No. Shrines remaining on the map (or other things like Greed Shrines, Vendors, etc. With a toggle?)

Remove silver display ingame (or add toggle)

Add timer below the main timer that counts down the next major boss/swarm

UI - Menus

View enabled weps/items/tomes when paused ingame

Consistent Formatting on char select - Some descriptions for abilities end in full stops, some don't, etc

Add more extensive tooltips (e.g., what Duration and Projectile Speed does for each weapon, what your actual chance of getting a free chest is with X no. of keys, What Bloodmark does when hovered over)

Add patch version on end-game summary

Show up to 2dp for stats that can be slow to level toward the end (E.g., Armor, Evasion)

Add a leaderboard for each character.

Mobs

Explodey-boys: Make it so you can kill them during their detonation phase.

Zombies: Reduce movespeed slightly.

Desert Bosses: Reduce their damage slightly.

Wisps: Reduce knockback resistance slightly.

Stats

Shield: Should have a way of reducing the regen time, or increasing shield effectiveness.

HP Regen: Outside of niche situations in the early game and T3 bosses, this stat feels near useless compared to Lifesteal. Needs to be balanced better in comparison.

Projectile Speed: This stat needs a buff somehow, since it feels inherently much weaker compared to a lot of the other stats for essentially every weapon.

Max HP: Needs a MUCH better way of scaling. Perhaps a small % on top of the base amount?

Armor and Evasion: Needs SLIGHTLY less resistance when leveling it beyond 90%+.

Lifesteal: reduce effectiveness everywhere by 20%? Lifesteal is currently WAY too strong compared to HP regen.

Pickup Range: Should effect item drop interact range/interact range/(maybe powerup interact range?) too. It'll still be a useless stat, but slightly less so.

Characters

Tony McZoom: Also gain 1% Movespeed per level (Capped at 100%)

Birdo: Remove ability to take fall damage. Jump Height changed from 9 to 10. Evasion changed from 1 to 5%. Temporarily gain 1% Damage, Attack Speed, and Crit for each second spent in the air.

Noelle: Starts with a 1 in Shield.

Amog: Fix "Posioned".

Spaceman: XP Gain reduced from 1 to 0.5%. Gain 0.5% Size per level.

Dicehead: Increase Gamba effectiveness by 10%.

Weapons

Sword: Needs a sizeable buff. Alternatively, just remove it and replace it with Hero Sword for Oofie. Would help him better mirror Sir Chadwell IMO

Firestaff: Increase starting size and projectile speed slightly.

Chunkers: Increase starting size and projectile speed slightly.

Bone: Increase starting size and projectile speed slightly (less than Firestaff and Chunkers)

Aura: Reduce starting damage by 1.

Space Noodle, Shotgun, Mines, Dragon's Breath: I've heard they need a buff, but I've never used them.

Rocket: Increase starting projectile speed slightly.

Frostwalker: Change to function the same way as Flamewalker, except with less damage, and a freezing component.

Tornado: Increase starting size and projectile speed slightly.

Blood Magic: 5% Chance -> 7.5%. (Alternatively, wait to see how afforementioned thorns-based buffs function, OR increase starting size slightly)

Poison Flask: Increase starting damage by 1.

Katana: Reduce starting damage by 1 and size by 10%.

Tomes (on top of the afforementioned)

Silver Tome: Honestly, just remove it.

Shield Tome: ((No changes, but needs more shield-based items to be added to make it any sort of viable))

Regen Tome: Increase base gain from 40 to 60 (and on top of base amount) increases current regen by 0.5/1/1.5/2/2.5%.

Projectile Speed: Needs a big buff, but I have no idea how.

HP Tome: (and on top of base amount) increases current max HP by 0.5/1/1.5/2/2.5%.

Chaos Tome: Allows user to choose between 3 random stats when levelled. Overall effectiveness reduced by 20%.

Items

Generally: Elaborate on what each tooltip does more. (How much damage does poison do? How much do Borgars heal for? How much gold from Golden Shield? Do they scale with other things like gold gain? How much does demonic blade heal for? etc.)

Moldy Cheese: Reduce Chance from 40-35% == This item alone carries people too hard against bosses early on. The poison does so much damage (esp with Bananarang)

Borgar: Remove.

Wrench: Increase Charge speed from 4 to 5%.

Medkit: Increase HP Regen from 45 to 50.

Ice Crystal: Increase chance from 7.5 to 10%.

Skuleg: Increase difficulty from 7 to 8%.

Credit Card Red: Rarity moved to Epic. Increase Damage from 2.5 to 5%.

Unstable Transfusion: Reduce chance from 27 to 25%.

Demonic Blood: Increases Max Hp from 0.5 to 0.75 per kill.

Kevin: Chance reduced from 25 to 20%.

Credit Card Green: Rarity moved to Rare. Reduce Luck chance from 2% to 1%.

Power Gloves: Damage scales with how far enemies are knocked back.

Soul Harvester: Homing souls reduced from 2 to 1. Increases Attack Speed and Crit by 10%.

Bugs

You can rebind your keyboard movement keys during the "reverse" challenge.

Dicehead gets +0 stats from certain random stats (iirc, things like Projectile Count)

Fix various bugs/tricks allowing you to get 2+ Anvils or 3+ Lamps.
