Animated prosthetics?

[Java Man]

Anyone know of existing rules for animated/golem limbs grafted onto a character? Or a good inspiration to build rules for this from?

It could provide an interesting, non-occult reflavoring of the Possessed Hand line of feats. Eventually, your golem limb could detach and move around by itself.

Kinda sorta?

Requirements: Craft Construct, Craft Magic Arms and Armor, animate objects, Small or Tiny construct

CR Increase: none

Cost: 27,000 gp

This modification can be performed on a Small or Tiny construct, such as an iron cobra or a homunculus. The creator modifies the construct such that she can slip it over her arm and control its actions as part of her own. The construct limb retains any melee attacks that the construct has, and the creator can use special attacks as if she were the construct (using the construct's attack statistics and effects), but treat the creator as the creature making attacks for the purpose of determining attacks of opportunity and other actions that could be triggered by an attack made by the creator.

The limb also provides the wearer with limited protection in combat, roughly equivalent to that of a heavy steel shield. The wearer is considered proficient in this shield. The wearer retains the remainder of her abilities.

A construct limb counts as a heavy steel shield for purposes of determining AC, weight, Dexterity modifiers to AC, and chance of arcane spell failure.

Presumably if you're missing most of your limb you could slip the construct limb over the stump and use it as a limb. GM's call whether it works if the limb is 100% gone.

There's the constructed pugilist Brawler archetype or the similar Jistkan Artificer magus. Interestingly, the rules for the pugilist's arm* make it no more difficult to attach an intelligence to the arm than your average sword

The constructed pugilist can improve her constructed limb as if it were a normal melee weapon. For the purpose of rebuilding the limb as a masterwork weapon, rebuilding the limb out of a special material, or adding certain magical special abilities to it, the limb counts as a one-handed melee weapon that costs 60 gp and weighs 6 pounds—though it is specially fitted to the constructed pugilist and can’t be resold or used by anyone else.

Ooh, totally forgot about the constructed pugilist. That would do nicely.

The Technology Guide has some rules on implants and cybernetic limbs that you could reflavor as magical. Uses a system of points that is determined by your Intelligence (how much 'stuff' your mind can mentally control) and Constitution (how much 'stuff' your body can physically handle).

The Ultimate Magic has rules on modifying constructs Link here for ease of reference. Construct Limb is similar in scope as to what you might be looking for.

The Limbjack template from Green Ronin's Advanced Bestiary sounds like exactly what you're looking for, and is fairly simple and elegant to implement.

Thanks for the tips folks, several bits I hadn't seen yet.
