Concentration Overhaul Mod

[size=5][b]Note - version change (1.0.x to 2.0.0)[/b][/size]

[size=3]If you installed an earlier version, delete the old  file ConcentrationOverhaul.pak first. New file: ConcentrationOverhaul2.pak[/size]

[size=5][b]What it does[/b][/size]

In the base game your character can maintain only one Concentration spell at a time. Cast a second one and the first ends — which means a support caster spends most of a fight choosing which single buff to keep.

This mod takes Concentration away from every spell that places an effect on a creature. They become ordinary spells: you can run as many as you like at the same time, they no longer replace one another, and damage no longer ends them.

[b]Affected[/b] — Bless, Guidance, Resistance, Shield of Faith, Spirit Guardians, Hold Person, Hex, Faerie Fire, Protection from Evil and Good, Blur, Haste, Enhance Ability and everything else of that kind.

[b]Not affected[/b] — Entangle, Darkness, Silence, Fog Cloud, Flaming Sphere, Moonbeam, Wall of Fire, Cloud of Daggers and the rest of the area and summon spells. These keep Concentration with everything that belongs to it: one at a time, a saving throw when you take damage, and the X below your portrait to end them.

[size=5][b]Why area spells are left alone[/b][/size]

For a buff, Concentration holds an effect on a creature. For an area or summon spell it holds a patch of ground or a creature it conjured. Take Concentration away from those and the game loses its grip on them entirely — the vines or the sphere would sit there with nothing left to end them. So they stay as they are.

[b]BG3 Script Extender[/b] 

[size=5][b]Installation[/b][/size]

Use Vortex / Mod Manager 

or:

Drop [b]ConcentrationOverhaul2.pak[/b] into your Mods folder


Then enable it in Vortex or BG3 Mod Manager and export the load order. Nothing else to configure. To uninstall, delete the file — the game returns to normal. Safe to add to a running playthrough.

[b]Spell mods work fine alongside this.[/b] The mod only ever changes the game's own spells, and it does so by a fixed list. Spells added by other mods are never touched.

Those spells also do not benefit. If a spell pack adds its own version of a buff and it requires Concentration, it will keep requiring it. Things can look inconsistent — vanilla Bless is free while a modded equivalent is not. And because a modded Concentration spell still uses the game's Concentration slot, it will still displace your Entangle.

[b]What does conflict:[/b] any mod that reworks Concentration itself, or that relies on those vanilla spells still requiring it. Another mod doing the same thing as this one is harmless — the change simply happens once instead of twice.

[size=5][b]What this changes about the game[/b][/size]

Worth knowing before you install:

[list]
[][b]These spells can no longer be interrupted by damage at all.[/b] That is a genuine power increase.[/]
[][b]Recasting no longer moves a spell.[/b] Cast Guidance on yourself and then on a companion and both of them keep it.[/]
[][b]Enemy spellcasters get the same treatment.[/b] Encounters become harder as well as easier.[/]
[/list]
If you want Concentration to still be a meaningful cost, this mod is not for you.

[size=5][b]A note on this version[/b][/size]

This is a rewritten, much lighter mod than it used to be. Earlier versions tried to manage those spells with their own penalty system, a dedicated ability and custom tooltips. That machinery is gone. What remains is a "no more concentration lite" mod: it removes Concentration where it does not need to be, and then stays out of the way.
