Lv 7 barb/ 3 bearwarrior: Blackbear
In his changed shape+ rage he should have 21 AC (10 + Chainmail+3 (8 total) + 3 Dex (the+2 natural armor is negated by the rage loss)
Armor melds when you shapeshift, as it doesn't fit on the new form. The AC is 10+3(dex)+2(nat)-2(rage), or 10+3+5-2 in Brown Bear form.
Attack: (not sure on that) 10BAB + 4 Str normal +4Str (bear form) = +18 for both claws +13bite (-5 penalty?)
Dmg: 1d4 + 8 (Strg mod) ? for claws and 1d6+12 for the bite ?
- I dont really know how the claw/bite damage is calculated.
Bears have 2 primary claws and 1 secondary bite. Thus, the claws get their full strength bonus(as per a 1H weapon), and the bite gets half strength to the damage(as per an offhand weapon).
Does the high bab give any additional attacks or just the 3 of the bear ?
Natural weapons do not gain additional attacks from high BAB.
Does the hardness of one weopn effect a sunder attempt ? It is a DR for items if you want to call it that way, but what it says is how hard something is.
So, if I have a large hillgiant with a large +1 greatclub, and he tries to sunder a +2 2H Maul weapon, could he destroy his own weapon as it isnt as hard as the +2 ?
A weapon never takes damage when attacking, unless a specific ability says so. Hardness cannot 'reverse' the damage(for IRL comparisons, a diamond is harder than steel, but you can still break diamonds with a steel hammer).
As long as the attack inflicts slashing or bludgeoning damage, it can sunder, but Fire and Electricity deal half damage before deducting hardness and cold deals a quarter. Ranged attacks inflict only half damage as well.
However, a +2 Maul has 14 hardness and 40hp, meaning you need to hit for 15 damage to do anything at all to the Maul, a somewhat difficult task with the 1d10(+8?) Greatclub without power attack.
Are there weapons that are actually better to sunder other weapons or shields?
The problem is that I dont want to replace the group weapons with just another weapon they would get when they slay an enemy. So a giant would be a good choice I guess, as the weapon is bigger, the str is increased for size... It could actually work.
What you want is just slashing(works on most weapon-like objects) and a whole lot of damage to get past hardness. Some weapons give a +2 bonus to hitting on sunder attempts, but thats trivial.
You can also look into the Mountain Hammer strike from Tome of Battle. It adds 2d6 damage to an attack and ignores all hardness and damage reduction.
I plan on using acid a lot in the next adv. part. Hoe exactly does that affect gear ?
Acid doesn't really do much to gear unless specifically aimed at it, when exposed to an attack, you have to roll a nat 1 on your save to even affect worn items at all, and they still have their defenses.
