Skills-and-Abilities VS EEex

House Rules and S&A, if you need links. Note that their proficiency systems aren't compatible with each other - the monk proficiency tweak is totally compatible with Skills and Abilities' new proficiency system, if you use it, but the "rebalanced proficiencies" and "rebalanced weapon styles" are not.

I mentioned it in my comment, but skills and abilities does that, spread across a couple different components. Two-handed attacks receive 1.5x the strength damage bonus (rounded down), and the revised Two-Handed style increases base damage, speed factor, and APR, making it a faster and more reliable way of dealing damage. The revised two-weapon style also slightly decreases your offhand damage, even at 3 pips - not much of a nerf, but overall I think the mod's changes to single-weapon, weapon and shield, and two-handed styles make them very tempting alternatives, since they all have their own strengths.

Skills and Abilities: Larger writeup on this coming soom™. Short version: a proficiency overhaul that takes BG1’s weapon groups as its starting point and adds new proficiencies which can better diversify character builds, such as Spellcraft (bonuses for arcane casters), Divine (bonuses for divine casters), and Swiftblade (bonuses while hasted). Other components overhaul Protection from Magical Weapons, change Turn Undead, and allow bards to pick locks and disarm traps (EEex required for these). Optionally changes weapon styles as well, incentivizing approaches other than dual-wielding, and adds HLAs drawn from 3.5E.

Check out releases on the right hand side. Download that and put the 'setup-xxx.exe' file and the associated folder in your game directory. Then just run the setup from there. Or use something like Project Infinity to setup, sequence, and install your mods at one time.

There is a nice mod (https://github.com/Gibberlings3/Skills-and-Abilities), that gives bards "Find Traps" and "Open Locks". Maybe this is something for you?

Note that you will need EEex for some of those components.

EEex mod has a "Scale interface" module that lets you do it incrementally. It is kinda complicated to set up though. After installing, you need to open "EEex_Modules.lua" located in /override, then swap the flag on B3Scale from "false" to "true" to active it. Then you either use the in-game cheat console and the command:

Bubb's EEex mod. There are technically 3 timers, but I only chose one - the one that shows rounds. There's also one for modal actions like Find Traps or Turn Undead and the third one for contingencies.

EEex needs to be installed prior to my ai and can be found here: https://github.com/Bubb13/EEex

Did you make your flail +3 thing on main floor? Starting with SoD, you start running into these creatures with some very specific immunities and buffs unless you look them up you would have no idea why you are getting your asses handed. This is why I suggest you get this at the very least, https://github.com/Bubb13/EEex. If you hit shift on anyone, you see list of spells active. Better yet use this like you own Beastiary: https://github.com/tapahob/BG2RadarOverlay, when you wonder why you cannot damage something or someone.

EEex is still in alpha, but working: https://github.com/Bubb13/EEex/releases
