Arcane pool, divine bond and masterwork

[Starglim]

The enhancement bonus granted by a paladin's divine bond or a magus's arcane pool stacks with existing weapon bonuses. Does it stack with the bonus to attack of a masterwork weapon? Neither ability specifies magical bonuses/enhancements. The character is for PFS.

RAW i do believe it does.

meaning a character with a master work weapon ant a +1 from a bond or pool ability SHOULD have +2 hit/+1 damage

[d@ncingNumfar]

Enhancements always overlap with the bonus from masterwork weapons.

[Skylancer4]

The enhancement bonus is still subject to the stacking rules, when they say "stack" it means it doesn't overwrite the existing properties. If you had +1 flaming burst weapon and then it got a +2 enhancement bump from another ability it would end up +2 flaming burst.

[Name Violation]

These bonuses can be added to the weapon, stacking with existing weapon enhancement to a maximum of +5. Multiple uses of this ability do not stack with themselves.

using one of the listed abilities adding a +2 enhancement to a +1 flaming longsword DOES make a +3 flaming longsword, not +2.

masterwork is an enhancement to hit.

its a weird corner case in the rules of having a magical +1 stack with masterwork +1 to hit

[Name Violation]

if it didnt work, then a 3rd or 4th level bladebound magus couldnt use arcanepool at all on their black blade, since its +1 and they can only grant +1, but since it stacks they CAN make a +2 blackblade at 3rd level

[Skylancer4]

The enhancement bonus from masterwork and an ability that adds an enhancement bonus do not stack... the enhancement bonus from masterwork is non magical. When you get a magical enhancement bonus that modifies a masterwork weapon, they don't get added together, it becomes a magical weapon (instead of non magical masterwork) with an enhancement bonus equal to the higher of the two bonuses. If they were both +1 enhancements, you would still just have a +1 enhancement total. If it was a +1 non magical masterwork enhancement and a +2 magical enhancement, it would be a +2 enhancement total (+2 enhancement [highest bonus] takes precedence over +1 enhancement).

The rules for stacking are in the PFRPG core book, maybe Name Violation hasn't read them, but they are unfortunately off the mark on this particular subject unless the ability specifically states it over rides the stacking rules.

[ShadowcatX]

Normally, Skylancer, you would be correct. However, the abilities being discussed here specifically state that they stack, not overlap. You should really read the specific abilities before telling someone else that they're wrong. A magus, can indeed spend a point from his arcane pool to turn his +1 weapon into a +2 weapon.

[Skylancer4]

I am incorrect about the magical enhancement bonus, I have just read the abilities in question. And so my example was bad, my apologies. However in the case of masterwork weapons, it still doesn't stack, which is what the OP's question was about. It is specifically called out that you must spend at least a +1 bonus on making it "magical" before adding anything additional properties. You won't get a +2 "to hit" and +1 "to damage" by just adding a +1 enhancement bonus. The magical enhancement bonus still overwrites the masterwork bonus as per the normal rules.
