AC modifiers

[valurin]

Is there a comprehensive description of how AC modifiers work on the server? Can someone please post the link?

[appleseedy]

nwn wiki should help but in general only dodge AC stacks

[valurin]

Thanks, do you have a link? Also does the server follow the nwn wiki? AC stacks work the same?

It's standard to NWN. Each kind works on the highest modifier except unlisted and dodge AC types; dodge stacks to +20. Ride is substituted for Tumble when on horseback.

Armor, Shield, Natural and Deflection do not Stack, but every thing else can? 

Will "(AC modifier)" stack?

I don't understand the question. 'Everything else' is a fairly short list. Otherwise your first statement is correct; those four parts do not stack. To quote from the wiki, these are the source that are not typed and do stack, with caveats for use:

ability: dexterity (+1-122, but limited by the armor's maximum dexterity bonus) *
bonus: Specifications to the dodge AC bonus or penalty (versus alignment, racial type, or damage type)
class: monk AC bonus from level progression (+1-8) **
feat: armor skin (+2) **
feat: battle training vs. giants (+4 against giant-type enemies)
feat: bone skin (+2-16) **
feat: dodge (+1 against current target or last attacker) *
feat: draconic armor (+1-8) **
feat: expertise/improved expertise (+5/+10)
feat: mobility (+4 against attacks of opportunity) *
feat: monk AC bonus from wisdom (+1-122) **
feat: small stature (+1, or more generally the size modifier: -2 to +2)
item: armor base (+1-8) **
item: shield base (+1-3) **
skill: tumble (+1-8) *

* These sources of AC are normally lost when caught flat-footed. However, the uncanny dodge and defensive awareness feats allow the dexterity bonus (only) to be retained.

** These sources of AC do not apply when subject to a touch attack.

Different types (armor, shield, etc) will stack together. The same type (multiple sources of Deflection, for example) will overlap so you only get the best one. The exception to that is Dodge, which will stack with other sources of Dodge up to +20.

Let's say you have adamantine armor, which on FRC gives you +2 Armor. Then you have a Mage Armor spell cast on you (+1 each Armor, Deflection, Natural, Dodge). The +2 from the adamantine and the +1 from the spell will not stack together, so you still only get a +2 Armor bonus. You still get the other bonuses from the spell, since they are different named types (of course, those might themselves overlap with other Deflection or Natural bonuses you might have).

A lengthier breakdown of AC types and stacking can be found at nwn.fandom.com/wiki/Armor_class . I still find myself looking it up every now and then.
