Blunt/Piercing/Slashing THAC0 bonus/penalties vs. non-armoured enemies?

Hi - I know that Blunt/Piercing/Slashing weapons get different bonus/penalties to hit versus different types of armour (there's a good visual indication of the effects here: http://www.pocketplane.net/volothamp/chap6.htm ), but how does this work with enemies that aren't wearing armour, but have a natural AC? Is the AC bonus/penalty always +0?

BTW I'm not asking a question about *resistance* to different weapon types (e.g. skeletons are highly resistant to piercing damage), which affects damage, rather any THAC0 bonus/penalty - is there anywhere to look this up?

Does blunt still usually get the best THAC0 vs/ most enemies, not just those wearing armour?

So far as I can tell, damage type only affects THAC0 for armored opponents, but I don't generally play with to-hit roll feedback on unless I'm testing something. Someone who pays attention to all their attack rolls might have different observations.

Interesting question. I've noticed that spiders have nice AC against missiles, my characters almost always suffer penalties to their rolls when firing a missile to them. Or I may be wrong, confusing it with fatigue, melee penalty, etc.

Actually damage type does not affect THAC0 at all. It is the enemy AC that may be affected by a bonus or a malus vs. a specific damage types (AC modifier).

So against an enemy without armour all weapons are equally effective, unless the enemy has some kind of resistance or an AC modifier (e.g. from a weapon or an item).

I think you just misunderstood the mechanism behind it. Different weapon type dont get a bonus vs different armours.
The bonus/penalty is entirely determined by the armour. So it is better to say that different armours get bonuses/penalties to AC, rather than weapons getting bonuses/penalties to hit.

To answer you question, an unarmoured creature gets no special bonus or penalites against any of the weapon types.

Thanks, that's what I wanted to know, obviously te resistances a creature may have vs. certain types of weapon affects damage, rather than AC (e.g. piercing vs. skeletons), although if the creature holds a small shield or buckler, then they will have a worse AC versus piercing.

Can someone check spiders/ettercaps cre files? I suspect one creature item they are equipped gives them extra ac vs missiles? (Along with immunity to web effects, I think)

Spiders have a not droppable item called "Antiweb" with the following properties:


If I understand correctly, despite the name "Immunity to projectile", this will only make them immune to webs as the projectile type is "webtrav". However, I'm just guessing and I didn't test it in game, so I may be wrong. Maybe someone with more modding experience can confirm if this is indeed the case.
