The weakness/resistance rules are a bit ambiguous, and in running this AP it's far more relevant than it's ever been before as almost every demon is affected. I've hunted for answers, failed to come up with good results, and a lot of it seems to depend on a several year old forum comment from Mark Seifter which seems not great as a definitive rules source. Part of the reason this is an issue after all is because of how the remaster changed the rules on a few things, and that long predates the remaster.
First, quoting the relevant paragraph of the rules. Copied from AoN.
If you have a weakness to something that doesn't normally deal damage, such as water, you take damage equal to the weakness value when touched or affected by it. If more than one weakness would apply to the same instance of damage, use only the highest applicable weakness value. This usually only happens when a creature is weak to both a type of damage and a material or trait, such as a cold iron axe cutting a monster that has weakness to cold iron and slashing.
The leading consensus is that if an effect deals multiple damage types, these should each be treated as a separate instance of damage and weaknesses/resistances should be applied separately. This post is mostly made because this seems to present issues to me, particularly in the case of demons and holy weaknesses which is extremely relevant to this AP.
There is also the rule about non-damaging weaknesses, which can be used to make the argument that if you are damaged by an effect with the water trait, holy trait, or something else not associated with a specific damage type you apply that weakness on top of any that would apply from the damage itself as it counts as being touched or affected by something with that trait.
I'm not sure of the best way to word this, so I'm just going to present a few simple scenarios and ask how people think they're meant to work. For each scenario, I'm just asking which weaknesses if any proc, and how many times if you think they should apply multiple times.
Take a hypothetical demon, with equal weaknesses to cold iron, holy, and also cold.
1) A fighter hits the demon with a cold iron longsword with the frost rune.
2) A fighter hits the demon with a cold iron longsword with the holy rune.
3) A fighter hits the demon with a longsword with the holy rune.
4) A fighter hits the demon with a longsword with the holy and frost runes.
5) A fighter hits the demon with a longsword with the holy and flaming runes.
6) A holy sanctified champion hits the demon with a cold iron longsword.
7) A holy sanctified champion hits the demon with a longsword with the frost rune.
8) A holy sanctified champion hits the demon with a longsword with the flaming rune.
Assuming the one damage type = one instance rule is correct, this seems to be the answers to the above.
1) Applies cold iron for slashing and cold for cold damage from the frost rune.
2) Applies cold iron for slashing and holy for the spirit damage from the holy rune.
3) Applies holy twice, once for slashing and once for spirit. As the strike has holy due to the rune, so all the damage is from an effect with the holy trait. If holy is a non-damaging weakness, you can argue it procs once, from interacting with a holy effect, as it doesn't count instances of damage.
4) Applies holy twice and cold (or holy) once, a combination of scenarios one and three. If holy is a non-damaging weakness, you can argue it procs holy once and cold once.
5) Applies holy three times, once for slashing, once for spirit, and once for fire. If holy is a non-damaging weakness, you can argue it procs holy once.
6) Applies cold iron (or holy) once, because only one damage type was dealt with slashing. If holy is a non-damaging weakness, you can argue it procs holy once and cold iron once.
7) Applies holy once and holy (or cold) once, for the slashing and cold damage respectively. If holy is a non-damaging weakness, you can argue it procs holy once and cold once.
8) Applies holy twice, once for the slashing and once for the fire damage. If holy is a non-damaging weakness, you can argue it procs holy only once.
Also this one is mostly because it came up in discussions about this elsewhere, but is less relevant to Spore War so I am mostly including it for completeness.
9) A water kineticist uses their elemental blast to deal cold damage to a creature weak to both cold and water. Do you apply one weakness or both?
My personal reading, just off the rules in the book, was that one strike/impulse/etc. is one instance of damage, and holy modifies the damage similar to cold iron, so every single scenario above the answer is only the highest applicable weakness is applied. Even in scenario 9, my interpretation was that the non-damaging weakness rule is probably not meant to apply to double up on weaknesses if damaging effects have the relevant trait. I'm not sure this is correct though, and it's been an on and off topic due to Spore War for us for months now.
