[RPG] Does Lay on Hands against undead require a touch attack

Oh! Well, that turns it from some complex mass of edge cases into a simple proposition.

1. If you go by the completely psychotic RAW or the Wizards FAQed answer on natural+flurry, then the flurry would not drain but any additional natural attacks would. Of course you'd have to get additional natural attacks, which just being a human soul eater or whatnot wouldn't get you.

2. If you go by the more reasonable interpretation accepted as the answer on the other question, and that's how I'd rule, then I'd also rule that sure, it's a flurry but "with" natural weapons and so totally, the energy drain would proc on each. It says "touch" after all, and considering an unarmed attack not a "touch" stretches in-game-world credibility.

First off, dandwiki has a bad reputation. I'm not sure who this is with, but I'd personally suggest using d20srd instead.

Here's their excerpt on Incorporeal Creatures (as a subtype):

Incorporeal Subtype

An incorporeal creature has no physical body. It can be harmed only by other incorporeal creatures, magic weapons or creatures that strike as magic weapons, and spells, spell-like abilities, or supernatural abilities. It is immune to all nonmagical attack forms. Even when hit by spells or magic weapons, it has a 50% chance to ignore any damage from a corporeal source (except for positive energy, negative energy, force effects such as magic missile, or attacks made with ghost touch weapons). Although it is not a magical attack, holy water can affect incorporeal undead, but a hit with holy water has a 50% chance of not affecting an incorporeal creature.

So let's quick break this down with a list of things that ignore incorporeality:

• Magic weapons
• Creatures that strike as magic weapons (including sufficiently leveled monks)
• Spells, spell-like abilities, or supernatural abilities.

Of these, there is a 50% chance to ignore corporeally sourced damage (such as fire), but will always take damage from positive energy, negative energy, force effects, or things that explicitly target incorporeal targets.

So the answer is: You can always hit with anything (as normal), but you may not harm the incorporeal target.

However, if you are doing the appropriate types of damage, you will always do damage, while other spells may not-this is entirely dependent on the spell in question. Cure light Wounds? You're set. Burning hands? Flip a coin.
