Does slaying stack?

[jamm]

If you've got Sun's Messenger all your arrows are undead slaying, so to speak. Though the damage bonus from having blessed arrows still applies, so firing blessed arrows (regardless of type) will yield better results.

Also, what do you mean Sun's Messenger doesn't slay emperor liches? Are emperor liches not undead? That would be the first time I hear that...

slays them all right. but other undeads are often one-shotted

Well, it's a friggin' emperor lich, what do you expect?

@moomoo: You can only get a critical or not a critical. If you use a slaying weapon on the type it slays, you get a critical, full stop. Increased crit chances from the kitty ring, bracers of war or Find Weakness can't increase the likelihood of a critical if it's already guaranteed! Using a blessed weapon, or ammunition, increases damage against undead and demons by 50%, which has nothing do with criticals, that's why it works.

Apart from that, the ring of the master cat provides a source of Fate Smiles, which slightly nudges rolls in your favor, and thus should result in slightly increased damage output. But if you're using a slaying weapon against a type it slays, the best rings to use if you want to increase damage even more are... rings of slaying. Not because they are named that way, but because they add damage to what critical hits will double (in case of melee) or at least double, up to quintuple (in case of missiles).

Needless against undead. Though the bonus you would get to Dex from kitty ring would probably influence the damage.

[Silfir]

That's true! Same goes for bracers of war.

Ok, so what about: sun's messenger, find weakness at 100, kitty ring and bracers of war for good measure

My understanding is that technically the kitty ring and BoW don't actually increase your weapon's critical hit rate... they increase the critical hit rate of the kitty ring and BoW. So if you decide to bash monsters with them in melee, you'll get more critical hits, but it doesn't affect any other weapons.

JellySlayer, I know from personal experience that BoW AT LEAST increase CH rate of unarmed beastfighters. I also do not think that The Creator would trick us like that with the descriptions of items.

Either that, or I have been trolled... 7/10

That's what sorear's code-dived results seem to suggest:
CODE DIVED spoiler (highlight to view): Critical hit boosts are only applied from weapons, so the following will NOT improve your crit rate when equipped normally (but should if you use them as weapons)

Bracers of War: 8%
Ring of the Master Cat: 16%

What if you wield an one-handed weapon on your right hand and the RotMC on your left (i.e. on the 2nd weapon/shield slot)? Will it increase the weapon's critical hit chance?
