Will using a wand of Infernal Healing turn me evil?

Question

Two sessions ago, during our weekly Pathfinder game, my bard almost kicked the bucket. She got saved in time by the other players, but it was really close. So afterward, our (LN) inquisitor approached her and discreetly handed her a wand of 'Infernal Healing' with the instructions to use it next time, please.

Now, Infernal Healing has the [evil] descriptor and fluff-wise I always took it as some sort of subtle temptation. Yeah, it's useful, but it still works with devils blood/unholy water and you are kinda dealing with evil. Accepting help from devils - slippery slope and all. The bard recognized the spell, but is not worldly/wise enough to know what to expect from it.

I heard that using spells with the [evil] descriptor shift your alignment to neutral after 3 uses and then it's two more uses till you're evil. Further research turned up conflicting information. Soooo... is this true in Pathfinder? Does it apply to wands as well? And is this a slightly magical/mind-controlly thing or just mundane 'your PC is doing evil stuff, so they're evil now'?

Admittedly, it would be pretty funny if the CG (“nicest member of the party”, according to the inquisitor) bard slowly got corrupted with nobody noticing... the staff still has 40+ uses, after all....

Answer 1

According to the most recent rulebook on this topic, you are correct that casting evil spells corrupts your character's alignment.

The most recent main Paizo RPG line book that discussed this subject was Horror Adventures, which had this to say about casting spells that are aligned (page 110):

[...] Casting an evil spell is an evil act, but for most characters simply casting such a spell once isn’t enough to change her alignment; this only occurs if the spell is used for a truly abhorrent act, or if the caster established a pattern of casting evil spells over a long period. A wizard who uses animate dead to create guardians for defenseless people won’t turn evil, but he will if he does it over and over again. The GM decides whether the character’s alignment changes, but typically casting two evil spells is enough to turn a good creature nongood, and three or more evils spells move the caster from nongood to evil. The greater the amount of time between castings, the less likely alignment will change. Some spells require sacrificing a sentient creature, a major evil act that makes the caster evil in almost every circumstance.

Those who are forbidden from casting spells with an opposed alignment might lose their divine abilities if they circumvent that restriction (via Use Magic Device, for example), depending on how strict their deities are.

Though this advice talks about evil spells, it also applies to spells with other alignment descriptors.

This is where the "two evil spell castings turns you neutral and three turns you evil" guidance comes from. Note that it adds in all sorts of qualifiers: if there's a big delay between castings its less of a big deal, if you do it with good intentions it has less impact on your alignment, etc.

But maybe its better to not follow this one...

This rule has been seen as highly contentious by the Paizo forum community as it opens big and thorny questions like: "Can every evil npc simply use 2 uses of a wand of protection from evil on themselves to change their alignment to neutral temporarily and remove their vulnerability to the paladin's smite evil?" and similar problems.

While the context provided (core line rules book, no "optional rule" language) suggests that this is a base-line update to how aligned spellcasting works, your GM has the freedom to use or ignore this change as they'd like (and I think the forum consensus is that its best to ignore it :>)

Answer 2

Per the SRD on Infernal Healing

You anoint a wounded creature with devil’s blood or unholy water, giving it fast healing 1. This ability cannot repair damage caused by silver weapons, good-aligned weapons, or spells or effects with the good descriptor. The target detects as an evil creature for the duration of the spell and can sense the evil of the magic, though this has no long-term effect on the target’s alignment.

Thematically though, it probably shouldn't an option that a good-aligned group uses.

Answer 3

Using evil spells can change your alignment over time so can good spells. So if you are worried about it learn a spell with the good descriptor and use it from time to time than you should, at least, not move from neutral to evil.

Some spells like summon monster inherit the descriptor of the creature you summon, so summon monster to summon a creature with the good subtype, for example, should help with that.

When you use a summoning spell to summon a creature with an alignment or elemental subtype, it is a spell of that type.
