Can a wizard learn a spell from a divine scroll?

Straight forward question, is a wizard able to learn a spell and add it to their spellbook when the scroll is divine.

This comes up because the wizard technically has to UMD a divine scroll even if the spell is on both lists.

From the scrolls page (which affects casting a spell)

The spell must be of the correct type (arcane or divine). Arcane spellcasters (wizards, sorcerers, and bards) can only use scrolls containing arcane spells, and divine spellcasters (clerics, druids, paladins, and rangers) can only use scrolls containing divine spells

Adding Spells to a Wizard’s Spellbook

A wizard can also add a spell to his book whenever he encounters one on a magic scroll or in another wizard’s spellbook. No matter what the spell’s source, the wizard must first decipher the magical writing (see Arcane Magical Writings).

What does Divine Soul in Contemplative Prestige Classe means?

In the Contemplative’s Class Features description (pag 32 Complete Divine), it is written:

Divine Soul (Su): At 7th level, a contemplative gains spell resistance. Her spell resistance equals her class level + 15. In order to affect the contemplative with a spell, a spellcaster must roll the contemplative’s spell resistance or higher on 1d20 + the spellcaster’s level.

My question is about the classes involved in calculating spell resistance. For example, a Cleric 10 Contemplative 10 has spell resistance: a) 35 b) 25

How does the Divine Blessing of Triune work?

The description of the Divine Blessing of Triune says:

Triune: You can use a computer without having a user interface or hacking kit simply by touching it. You must still succeed at a Computers check to hack it if you do not have authorized access. Additionally, you have limited telepathy that functions only with constructs with the technological subtype.

Limited Wifi-Telepathy is great, and you still have to make a skill check to hack. However, what if you need to download or upload information and your only contact with it is touch? Can you store digital data within yourself, since the source of the ability is supernatural?

When it says “use a computer without having a user interface or hacking kit simply by touching”, would “use” in this case cover the transfer and of deliverance of data? How much data can user hold?

I’d like to know the limitations of this feat.

Does a humanoid possessed by a ghost register as undead to a paladin’s Divine Sense?

A Ghost (MM, p. 147) can possess a humanoid as per their Possession action:

Possession (Recharge 6). One humanoid that the ghost can see within 5 feet of it must succeed on a DC 13 Charisma saving throw or be possessed by the ghost; the ghost then disappears, and the target is incapacitated and loses control of its body. The ghost now controls the body but doesn’t deprive the target of awareness. The ghost can’t be targeted by any attack, spell, or other effect, except ones that turn undead, and it retains its alignment, Intelligence, Wisdom, Charisma, and immunity to being charmed and frightened. It otherwise uses the possessed target’s statistics, but doesn’t gain access to the target’s knowledge, class features, or proficiencies. […]

A paladin’s Divine Sense (PHB, p. 84) says:

The presence of strong evil registers on your senses like a noxious odor, and powerful good rings like heavenly music in your ears. As an action, you can open your awareness to detect such forces. Until the end of your next turn, you know the location of any celestial, fiend, or undead within 60 feet of you that is not behind total cover. You know the type (celestial, fiend, or undead) of any being whose presence you sense, but not its identity (the vampire Count Strahd von Zarovich, for instance). […]

If a humanoid was possessed by a ghost, then a paladin were to enter the room and use their Divine Sense, would the humanoid register as undead (or the undead nature of the ghost still otherwise show up on the paladin’s “radar”, such as detecting undead within the humanoid or something like that) or would the possession effectively render the ghost immune to being detected by Divine Sense?

Before high levels, can Salient Divine Abilities be balanced for players?

I’ve become interested in Salient Divine Abilities. This answer details some of the ways in which they can become absurdly imbalanced (even in comparison to an Epic level party). However, when I look through the prerequisites for the most absurd of these abilities (e.g. those that can easily affect multiple targets, allow no saves, or can rewrite reality), I find that they require very high levels or ability scores that I believe will be very hard for most PCs to achieve at a point where a normal 3.5e game would still be considered balanced (e.g. short of breaking the game, how would you get Cha 29 at level 10?). So for the sake of this question I will pick level 15 as an arbitrary point where we can assert that 3.5e is still a game that we need to worry about destroying the balance of.

This gives me my question: Prior to level 15, is there any way to give players access to Salient Divine Abilities that would not destroy game balance? An answer will ideally either give an example of a game-breaking Salient Divine Ability that is easy to access for most PCs or will, by means of several examples, show that the power of the Salient Divine Abilities that PCs can access do not greatly exceed the power of what they can realistically already access at their level. Finally, we will assume that the DM does not ban any particular abilities and that the players can gain any Salient Divine Ability that they qualify for.

Changing Divine Smite to Necrotic Smite?

I have a True Neutral Paladin that is also a Fallen Aasimar. He has fully embraced darkness, letting it into his heart and spurned his celestial heritage. He hasn’t gone fully evil purely because he still wishes to help and cannot bring himself to kill/hurt innocent people. He came to me with an interesting question however, wishing to re-flavor his Divine Smite.

So, could Divine Smite (Radiant Damage) be re-flavored to call it Necrotic Smite and have it dealing Necrotic Damage instead?

Would you let him have access to both Divine and Necrotic strikes since he still is capable of casting divine as a Fallen Aasimar?

Does Improved Divine Smite work in an Antimagic Field?

At 11th level, a paladin gains Improved Divine Smite. This means (PHB p85):

you are so suffused with righteous might that all your melee weapon strikes carry divine power with them.

Given that the normal Divine Smite requires a spell slot to be expended, I took it to be considered as a spell and therefore unusable within an Antimagic Field (PHB, p213):

This area is divorced from the magical energy that suffuses the multiverse. Within the sphere, spells can’t be cast, summoned creatures disappear, and even magic items become mundane. […] Spells and other magical effects, except those created by an artifact or a deity, are suppressed in the sphere and can’t protrude into it.

Improved Divine Smite, however, appears to be a quality innate to a paladin of 11th level or higher. Is it affected by an Antimagic Field?

Does a Divine Soul Sorcerer’s alignment affect their choice of Divine Magic affinity?

The Divine Soul Sorcerous Origin from Xanathar’s Guide to Everything (page 50) has the class feature Divine Magic at level 1. It allows you to pick a “free” extra spell based on having an “affinity” with the source of your divine power.

In addition, choose an affinity for the source of your divine power: good, evil, law, chaos, or neutrality. You learn an additional spell based on that affinity […]

This choice also affects later class features, such as Otherworldly Wings (the level 14 subclass feature):

The affinity you chose for your Divine Magic feature determines the appearance of the spectral wings: eagle wings for good or law, bat wings for evil or chaos, and dragonfly wings for neutrality.

Does your character’s alignment have any influence over your choice? Can a Chaotic Evil sorcerer choose Law, or can a Lawful Good sorcerer choose Neutrality, etc.?

I’m inclined to assume that they are unrelated given that it doesn’t explicitly say that it is restricted by your alignment, but the fact that it uses the terms good, evil, law, chaos, makes me doubt myself. I can also see this terminology encouraging a DM to say that it does influence your choice.
