In vanilla, Lightning Charges check when you deal damage if you have >= 5 charges and then apply a dummy status that applies the damage (this prevents damage riders from applying, not needed anymore, since honour mode gave the option to disable riders and bonuses in the deal damage function). The major change: There is a technical status applied that culls any charges above 7 (vanilla). It is always applied alongside lightning charges. I use this to check your current lightning charge count and if it is >= 5 I apply a status that immediately reduces your charges by -5. On the next attack, it will be consumed to deal extra discharge damage. This status is visible with the 2nd icon displayed here.

Now what impact does this actually have? Previously, when you reached 5+ charges, items would stop generating charges until you discharged your charges (they have a condition that you need to have <5 charges). Now they will continue to generate charges as your 5 charges are immediately consumed to grant you the discharge status, instead of when you deal damage the next time.

This is also how my Chain Lightning Charges for the Tempest Displacer Ring work in my Druid Wildshape Item mod.

5e Spells: There should be no conflicts since it only adds spells and doesn't edit vanilla ones.

In general:
The main reason for compatibility issues is two mods editing the same thing. Depending on the exact thing this can be very broad or narrow. You don't have to be a modder or understand these terms, just know there is different kinds of ways the game stores information:

• Root template: Has to be entirely overwritten to be changed, so two mods changing different things still aren't compatible
• Stats entry: Can be inherited, merged, changed, if the same thing is changed it'll overwrite, otherwise changes merge (unless the entry is entirely overwritten which a lot of novice modders do)
• Progressions/list entry: Like root templates, but compatibility framework allows merging changes for proper compatibility
  

Should not matter - if you use mods that edit the same spells there might be conflicts.

In general:

• The mod loaded later/further down the list overwrites
• Example: Mod A (loaded first) changes the field 'AmountOfTargets' on Firebolt to 2 and Mod B (loaded later) has it set to 1 then Firebolt will only hit 1 target
• If the mods change different fields and use self-inheritance (recommended) then the changes merge - which can be desired or not
• Example: Mod A (loaded first) changes the field 'AmountOfTargets' on Firebolt to 2 and Mod B (loaded later) changes Firebolt to deal 1d12 damage - if the mods use self-inheritance, you now get a Firebolt that hits 2 targes for 1d12
  

I appreciate constructive feedback. If you think something is too strong or weak or could be done better you are welcome to comment. Note that I may have a reason (design-wise or functionality wise) why something is the way it is. Also please be aware that maybe your +300% health playthrough with 17 custom classes/races and 15 turn combats of running away and letting enemies rot from damage over time is maybe not the average player experience.

Please try to provide feedback as 'user story'. Tell me what happened, the circumstances, what fight, what difficulty etc. - otherwise its fairly hard for me to judge whether something I designed is problematic in general or just in specific scenarios. That information is very important for me to understand the nature of the issue.

As example: "Your rebalanced blight is way too strong!" is not nearly as helpful as "Blight carried my fight against X entirely by itself, because I lured the enemy out of the room, they clumped up and every hit dealt 3-5 damage to 8+ enemies" - even though the second is still just a single sentence.

Often I get questions like "Can you make a version without X?" - I can, but I will not. There is a few things about BG3 mods one might not think about right away. The work involved is high and modders usually make a mod for themselves with the courtesy to make it available to others and maybe spend extra hours to maximize compatibility and make it more broadly appealing.

An additional version means probably at least 1h or 2h of making that alternate version and uploading it, and then several hours maintaining that version, as now every change made to the original mod has the be copied over to that version. Every upload takes twice the effort (packing two files, updating version, updating description, updating changelog, ensuring you are overwriting the correct file etc.).

There is a lot of unfortunately quite popular mods on nexus that are the lowest effort stat overwrites that don't care about any of: Compatibility, fixing tooltips, adding new mechanics, designing well, making anything new or properly testing - they just slap existing passives on something that already exists. Updates aren't required or don't happen. Of course they can have 10 versions of that mod, because it took them almost longer to upload that version than make it and they aren't going to maintain it.

So before you ask "Can you make a seperate version" ask yourself - what are you asking exactly? A stranger to spend multiple hours of their time for free to make a version that barely appeals to a fraction of people over the original mod and even less people that didn't download the original but would download the other version (= minimal gain in quality and popularity).

More importantly, you are asking the person to take that time away from making a new mod, something that far more people would enjoy far more (probably even you).

Now lets talk money for a second. Depending on how passionate a modder is about your request they might make it for free (since they would have done it themselves anyway) or ask a reasonable price of say 40€ (=44$) an hour. Now look at the highlighted numbers again and do the math. An alternate version is most definitely not the former (something the modder is passionate about) or it would exist already. Are you willing to pay that? A fraction of it?

That is all to say, I still appreciate constructive feedback. Many good changes and additions have come from comments. All I want is for people to stop and think for a moment what they are asking.
