Arcane Duelist and bonding a weapon

[SlimGauge]

Have I got this right ?

At level 5, and Arcane Duelist Bard gets Arcane Bond (Ex)

Arcane Bond:

Arcane Duelist's Arcane Bond (Ex): At 5th level, an arcane duelist gains the arcane bond ability as a wizard, using a weapon as his bonded item, allowing him to cast any one additional spell that he knows once per day. He may not choose a familiar or other type of bonded item. He may use the hand holding his bonded weapon for somatic components. This ability replaces lore master.

This bond works "as a wizard". The wizard's arcane bond works as follows

Arcane Bond:

Wizard's Arcane Bond (Ex or SP)Wizards who select a bonded object begin play with one at no cost. Objects that are the subject of an arcane bond must fall into one of the following categories: amulet, ring, staff, wand, or weapon. These objects are always masterwork quality. Weapons acquired at 1st level are not made of any special material. If the object is an amulet or ring, it must be worn to have effect, while staves, wands, and weapons must be wielded. If a wizard attempts to cast a spell without his bonded object worn or in hand, he must make a concentration check or lose the spell. The DC for this check is equal to 20 + the spell’s level. If the object is a ring or amulet, it occupies the ring or neck slot accordingly.

A bonded object can be used once per day to cast any one spell that the wizard has in his spellbook and is capable of casting, even if the spell is not prepared. This spell is treated like any other spell cast by the wizard, including casting time, duration, and other effects dependent on the wizard’s level. This spell cannot be modified by metamagic feats or other abilities. The bonded object cannot be used to cast spells from the wizard’s opposition schools (see arcane school).

A wizard can add additional magic abilities to his bonded object as if he has the required item creation feats and if he meets the level prerequisites of the feat. For example, a wizard with a bonded dagger must be at least 5th level to add magic abilities to the dagger (see the Craft Magic Arms and Armor feat in Chapter 5). If the bonded object is a wand, it loses its wand abilities when its last charge is consumed, but it is not destroyed and it retains all of its bonded object properties and can be used to craft a new wand. The magic properties of a bonded object, including any magic abilities added to the object, only function for the wizard who owns it. If a bonded object’s owner dies, or the item is replaced, the object reverts to being an ordinary masterwork item of the appropriate type.

If a bonded object is damaged, it is restored to full hit points the next time the wizard prepares his spells. If the object of an arcane bond is lost or destroyed, it can be replaced after 1 week in a special ritual that costs 200 gp per wizard level plus the cost of the masterwork item. This ritual takes 8 hours to complete. Items replaced in this way do not possess any of the additional enchantments of the previous bonded item. A wizard can designate an existing magic item as his bonded item. This functions in the same way as replacing a lost or destroyed item except that the new magic item retains its abilities while gaining the benefits and drawbacks of becoming a bonded item.

Interpreting that by replacing "wizard" with "arcane duelist bard"

Play has already begun, so it's too late for the ADB to receive a masterwork weapon at no cost.
Does the ADB pick a mastwork weapon she already possesses to bond with ?
Does doing so cost 1000 gp as if the (non-existant) bonded weapon from level 1 was lost ?

If so, the ADB seems to lose out twice, once on not getting a MW weapon and once on it costing a grand to activate a class feature. I searched the old threads, but I don't see a definitive call on this. I'm going to suggest to the GM that the missed "free masterwork weapon" should cancel out the cost to form the initial bond with an already posessed MW weapon, but this isn't RAW (might be RAI, but you never know).

Regardless of the answers to the above, have I got the following right ?

Assume a bard of CL6 but bard level 5 (multi-classed with fighter but with the magical trait that boosts CL).

Bonds with an existing adamantine longsword. To put an enhancement on this sword normally takes the Craft Magic Arms and Armor (Item Creation) feat, but because this is her bonded weapon, this requirement is waived. The prerequisite of CL5 remains, but this is met by all ADBs because they don't get the arcane bond until level 5 anyway.

The creator must have a caster level equal to or greater than 3 times the enhancement bonus. This means a limit of +2. Can this limit be exceeded by increasing the DC of the Spellcraft check by 5 ?

The base price for a +2 is bonus squared x2, or 8000, so the cost is 4000 in materials? This will take 8 days (1 day / 1000 of price (not cost)) ? And the DC of the spellcraft check is 5 (base) + 6 (caster level) for a total of 11 ? Can the ADB take 10 on this check ?

Let's assume instead she bonded with an existing +2 rapier and wishes to add the "Dueling" property from the APG to it.

Dueling Weapon Property (APG):

Dueling: This ability can only be placed on a melee weapon. A dueling weapon (which must be a weapon that can be used with the Weapon Finesse feat) gives the wielder a +4 enhancement bonus on initiative checks, provided the weapon is drawn and in hand when the Initiative check is made. It provides a +2 bonus on disarm checks and feint checks, a +2 bonus to CMD to resist disarm attempts, and a +2 to the DC to perform a feint against the wielder. Faint transmutation; CL 5th; Craft Magic Arms and Armor, cat’s grace; Price +14,000 gp.

Doing this will cost her 7000 gp in materials, take 14 days of work and require a DC 10 Spellcraft check, DC 15 if she doesn't know Cat's Grace ? If her buddy the wizard supplies the Cat's Grace, does he have to make any rolls ?

Suppose she wanted to add "Keen" instead of "Dueling".

Keen Weapon Property:

Keen: This ability doubles the threat range of a weapon. Only piercing or slashing melee weapons can be keen. If you roll this property randomly for an inappropriate weapon, reroll. This benefit doesn’t stack with any other effect that expands the threat range of a weapon (such as the keen edge spell or the Improved Critical feat). Moderate transmutation; CL 10th; Craft Magic Arms and Armor, keen edge; Price +1 bonus.

This takes the total plus from +2 to +3, meaning the price goes from 8000 to 18000. She'll owe half the difference in materials, or 5000. She'll need 10 days or 18 days (the difference in price or the total price) ? The caster level requirement will be CL 10, since you take the higher of the special ability or the enhancement. So because she's not CL10 and doesn't know keen edge, the spellcraft check DC is 5 (base) + 10 (caster level required) + 5 (not meeting CL requirement + 5 (not knowing keen edge) for a total of 25 ?

EDIT: fixed one spoiler not showing correctly

Tacking something on if ya don't mind, as this reminds me of something-

Arcane Bonded items and the DC 20 spellcraft check. Does the Duelist suddenly have to make those at level 5? Because if so, that kinda sucks- getting -worse- at spellcasting when you level, even if only once.

Bueller ? Anyone ?
