What are the possible balance implications for houseruling INT as Paladin’s spellcasting ability and class features?

Related (yet different): What is the source of a Paladin’s spell-casting ability?

Related (strongly): What are the impacts of changing a Ranger’s spellcasting ability? (I don’t know if everything that’s said about the Ranger is applicable to the Paladin)

My player wants to create (L1) an investigator-type paladin (of the Inquisition) and asked that Intelligence becomes the character’s spell-casting ability and, if possible, also class features ability (e.g. Lay on Hands).

PHB states that:

Charisma is your spellcasting ability for your paladin spells, since their power derives from the strength of your convictions. You use your Charisma whenever a spell refers to your spellcasting ability. In addition, you use your Charisma modifier when setting the saving throw DC for a paladin spell you cast and when making an attack roll with one.

Since they are not asking for extra skills than the ones already provided by race, class & background, i.e. Paladins can pick from two Charisma skills (Intimidation, Persuasion) and one Intelligence skill (Religion) at character creation, I don’t see any system-unbalancing issue in this approach.

To be clear, my issue is not the fluff of “the strength of convictions” (I’ll probably trump it as “rigorous reasoning” ala Sherlock Holmes) but whether the PC becomes over/under -powered, compared to the normal Charisma-based option, over the short and long run.

In case it is relevant, it is a Human-only (for PCs) campaign, with options only from PHB (feats included) excluding multi-classing.

Can anybody ‘splain to me in an email correspondence how to use Thunderbird’s ability to use for vim?

The only editor I can use with ease is Mutt. It allows use of vim/gvim/ed/vi/nvi …&c. Most email these days requires that I use Thunderbird. I’ve found articles that explain how-to use T’bird with vim/gvim, but don’t quite understand what the “magic commands” are that let me configure this.

Can anybody help me?

New to D&D, chances on ability checks [on hold]

I’m going through the DM Guide and I see that DCs should be based on the “average person”. What I’m having a hard time with is that if someone has a +5 in history(quite knowledgable), and the task is “hard”(dc20) then they still only have a 1/4th chance of success.

It seems to me the chances don’t quite add up.

Do I have this correct? How can I (or should I?) express that a person who doesn’t know History has no chance of passing a history check, but a historian should probably have a better than 1/4th chance.

I am a player now, but wish to be a DM in the future.

I guess my bigger issue is the difference between an average person and someone who is well trained. Someone with a 0 in Arcana has a 25% chance of success against a “medium(dc15)” task. Where as someone well trained in magic(+5 arcana) has only a 50% chance. That seems quite out of whack to me.

If two Lore Bards used cutting words on an ability check or attack, would they stack?

Let’s say the party had two Lore Bards, and both used cutting words on a creature who tried to attack. Does that stack since they are separate penalties and not enduring effects (like bless), or would it still fall under the “same name features don’t stack” rule?

Do ability scores have any effect on casting Wish spell

Is a sorcerer able to cast wish in the same way and as effectively as a wizard can?

I had a friendly argument lately. I wrote my hypothetical wish somewhere around draconic sorcerer level 3. Being a lawyer I wrote about page long Wish with the intention to become a real dragon.

Recently I get into a theoretical discussion with my Dungeon master and his position about the matter was that my sorcerer wouldn’t be able to cast this spell this way (meaning with my page-long wording) because he wouldn’t be intelligent enough to phrase it in that way. My Dungeon master would let a wizard cast it in that way though. Implications of this are that in this way a sorcerer is straight-up weaker casting wish than a wizard is.

My argument was that when we look at sorcerer versus wizard their casting abilities differ and sorcerers are probably not as smart as wizards but while casting a Wish sorcerer can offset this by the fact that the magic runs through their blood. Their casting is natural, innate. They might not be able to phrase the Wish that well but that nature of their casting should offset that (basically sorcerers should be able to use their charisma for formulating Wish or at least). And both classes have the spell in its corresponding spell lists.

“You might be able to achieve something beyond the scope of the above examples. State your wish to the DM as precisely as possible.”

Considering above highlighted part of the spell does Intelligence of caster or any other of his ability scores affect how well is that said caster able to cast Wish spell?

Is there a spell that grants the ability to see in both magical and non-magical darkness?

I’m looking for a spell which I thought existed, but now I’m unable to find it. The main effect of the spell was to grant the see-in-darkness ability (darkvision + see in magical darkness, both with no range limit much like normal vision).

The only spell which I can find is true seeing, which is a high-level spell.
