I'm looking for a 3.5 spell for my Pathfinder game

[JiCi]

I'm looking for a spell that I think has been published in a 3rd-party book that I can't find anymore, and I'm asking for your help.

The spell I'm looking for is a spell that allows the caster to merge a magic item into his body or into the body of someone else. The item is still functional, but isn't present on the caster's body anymore, meaning it cannot be stolen nor removed. Furthermore, and here's the interesting part, if the magic item is intelligent, it remains so even if merged.

Can you guys help me out and tell me what's the spell's name and where to find it ?

Thanks in advance !

What (classes') spell list was it from? I remember a "hide weapon" spell on the assassin's list, but nothing else comes to mind.

Sounds like meld object, which is in either the Relics and Rituals book 1 or 2, Sword and Sorcery line.

The closest similar spell I know off the top of my head is absorb weapon, but that only applies to weapons and they don't function at the time.

Yeah 'meld object' Relics and rituals book 1.
