Despite the numerous updates DD2 has received fixing bugs, some still remain in the game, and some have even been here since day 1. The purpose of this mod is squashing those lingering bugs up and until the devs fix them officially. This patch also includes a few tweaks that can't really be classified as bug fixes, but improve the experience so much that I included them anyways.

Installation 

Install it as usual with Fluffy Mod Manager, by dropping the zip file into the mod manager. Don't forget to install the requirements as well.

Configuration

You can open the main script, _UDD2P.lua (located in gamedir/reframework/autorun), with any text editor. There, at the very start, you'll have config options that you can set to true or false. Every part of the mod is toggleable like this, though a few of the changes are lumped together for performance reasons.

Bugs fixed by this mod

• Some bosses, most notably Griffins, receive about 6 times less damage from arrows than from melee attacks. This difference is so extreme that shooting a Griffin in the head, it won't play the weakspot sound. This patch sets those values to be the same as for melee attacks. It only affects Griffins, Wights and Liches.
• Thief's dash attack is bugged and will miss every other hit if you spam it against an enemy. This patch fixes that.
• Goblin torches can hit you dozens of times in a row if you're near them after they're thrown, resulting in massive damage. This patch makes it so the torches can only hit each character once.
• Shells created by the player don't automatically ignore friendly NPCs in combat. This isn't a problem in vanilla but if you're using Skill Maker or Dullahan with their custom skills, the shells created by those skills will hit friendly NPCs in combat. This patch includes a global fix for that.
• If you break one of the horns of a Minotaur with a melee attack while its charging, your attack will deal 25x more damage to it, often resulting in one shotting the Minotaur. This patch removes that interaction.
• Levin's sound has been bugged since release and won't play all the thunderbolt sounds. With this patch, all of them play correctly.
  

Small gameplay tweaks

• Enemies will no longer yeet you off instantly when you're standing on them (for example when you open a Drake's heart while standing on it). Instead, a minimum of 2 seconds spent in the "unbalance" animation are needed before you're yeeted off an enemy.
• NPCs will no longer freak out if you draw your weapons near them. Note that their affinity still decreases.
• Maelstrom and Meteoron's magick damage no longer damages golems. Note that Meteoron's physical damage will still damage them.
• Your damage no longer scales with body size.
• The angle that makes you start sliding on a slope has been increased from 38 to 48. This makes it harder to unintentionally slide down slopes.
• Pawns will no longer die to the brine but they'll spawn back at the position where they jumped off, just like the player.
• Fall damage is a bit more lenient. There are several fall damage options to choose from in the script.
  

Quality of life tweaks

• You can now run during the tutorial.
• Pressing one of the two dialogue skip buttons (A/X on controller, F/Spacebar on keyboard) will now actually skip to the next line of dialogue, rather than simply skipping to the end of the current line of dialogue.
• You no longer need to be near your pawns to trade items with them or change your main pawn's skills.
• Sprinting out of combat and with your weapons sheathed will no longer consume stamina.
  

Miscellaneous or cosmetic tweaks

• It can now rain at night (yes, it couldn't before).
• Hitting weakspots with magick attacks now triggers the weakspot sound, just like with melee attacks.
• Stray pawns will no longer approach you and force you to talk to them.
• The Wyrmfire visual effect that plays on your gear when it's maxed out has been removed. Credit to Shadowcookie for figuring out a way to implement this that is hundreds of times more efficient than the other mod doing this.
• When you attack or use a skill while your weapon is sheathed, you'll now perform the corresponding attack or skill, rather than just drawing your weapon.
  

Bugs not fixed by this mod

There are still some issues that aren't fixed by this patch either because I didn't know how, or because fixing them might interact negatively with other parts of the game.

• Supposedly, guards in Bakbattahl are meant to either kick you out or attack you if you stay in the city for too long without a permit. But this doesn't happen (or if it does, it's after a comically long amount of time), they simply run up to you and ask you what is your business there. 
• Dynamic wounds on bosses were broken by a game update, and they're still broken to this day (at least, I'd like to think they weren't intentionally removed for performance reasons).
• Very rarely, Heavenly Shot will stagger downed bosses before it actually damages them, making you miss your shot.
• Some spell hitboxes are unable to hit certain body parts on bosses. Levin is most notorious for this, it cannot hit a Cyclops eye for example. The spells seem balanced around this so changing this would probably require some balancing for a few spells.
• AoE attacks (mostly spells) can hit several weakspots on Purgeners at once. This doesn't happen for any other enemy in the game, and it makes most spells ridiculously effective against Purgeners.
• When killing an alpha red wolf, all small enemies will flee in fear, rather than just the rest of the wolves.
  

FAQ

• Some of these overlap with small mods you've already done. Should I uninstall those?
  

Yes. The fixes and tweaks included here are sometimes even improved versions of the old mods. I've mostly hidden those other mods because I don't want to support several versions on several pages of these tweaks. These are all the mods I've released in the past that are included here: Archer Weakspot Fix, No distance pawn restrictions, Faster dialogue skip, Magic weakspots, No stamina cost out of combat, Thief dash attack fix, Goblin torch fix. As for Sliding Controller, it should overwrite this patch, so if you want a custom value for the sliding slope, feel free to use it.

• Some of those "bugs" may have been intended.
  

I obviously don't proclaim absolute authority over whether the devs intended Archers to be 6 times weaker than Fighters against Griffins or whether they intended Minotaurs to be easy to kill in one hit. Nonetheless, I think changing both of those things makes the game better. Feel free to call them "tweaks" rather than bug fixes.

• Why remove damage scaling with body size?
  

Your base damage is your weapon's strength/magick plus your own strength/magick multiplied by this body size multiplier (which ranges from 0.9 to 1.1). Setting this modifier to 1.0 for all body sizes makes it easier for me as a mod developer to mess with the base damage of attacks. If you don't like it, you're free to turn it off in the script, though you really won't notice a difference, it's usually less than ±5% damage.

• Will you make a script generated UI for the mod?
  

No. It takes a lot of effort to do that and, realistically speaking, you'd open it once and never use it again. Hence, having simple config options in the script itself, which can be opened with any text editor, seems like a far better choice.
