I'm wanting to add a spell to a set of existing Bracers of Armor +2. Do I use the caster level of the Bracers for the spell effects and price, or the lowest possible CL for the spell?
The spell is Long Arm, for reference.
BoA have a caster level of 7.
1st, as this is a custom made item get the gm approval.
next when you have that (or if you ARE the gm). the caster level of an item with many abilities uses the higher of them. in case of a spell the minimum caster level is the minimum to cast said spell and the maximum is the spell caster casting ability -in custom items and spell trigger items.
-normal listed items (not spell trriger) that have a cl which is higher then the item's cl can be bypassed with a +5 to craft dc. if it's in the requirement part. if not it's made with said cl even if the caster level of the crafter is lower. such as lower level caster making pearl of power 1)
Caster Level (CL): The next item in a notational entry gives the caster level of the item, indicating its relative power. The caster level determines the item’s saving throw bonus, as well as range or other level-dependent aspects of the powers of the item (if variable). It also determines the level that must be contended with should the item come under the effect of a dispel magic spell or similar situation.
The CL of the magic item is the CL of the spell cast.
If the Longarm spell is cast #/day, then it will share the bracer's CL. If it is continuous, then it does not need to be the same CL. However, a case could be made for a dispel to use the lower CL from the continuous enchant.
