Feat: EQUIPMENT FORM
Cost: 3 points
Prerequisites: Able to invoke Shapeshift on yourself at PL6 (or equivalent effect / racial ability).
As a major action, you can transform yourself into a piece of equipment and equip yourself onto a willing target. Your initiative changes to match theirs at the start of the next round. Choose whether you become a weapon or a piece of armor. (If becoming a piece of equipment that can serve either purpose, pick which one to function of when you transform.)
Tier 1 - You can only perform minor actions on your turn while being wielded/worn. Actions you perform (as in, not actions the wielder/wearer is performing using you) still utilize your own stats.
WEAPON FORM: You grant Advantage 1 to your wielder on any attacks per 3 points you have in the stat they are using for that attack.
ARMOR FORM: Damage is split evenly between you and your wearer (rounded up). If a hit would reduce you to 0 hp while you are being worn, you are instead reduced to 1 hp and revert to your normal form, appearing in a random square adjacent to your wearer.
Tier 2 - You can also take a move action during your turn while being wielded/worn. (If you are being worn as armor, you can move your wearer if they are willing.)
WEAPON FORM: You grant +1 to the wielder’s attack stat per 3 points of Alteration. (This can allow the wielder to inflict a Bane of a higher power level.)
ARMOR FORM: You grant +1 to all of wielder’s defenses per 3 points of Alteration.
Tier 3 - You still get your major action during your turn while being wielded/worn. (You can now take Focus Actions as normal.)
VARIANT OPTION: Symbiote Armor - Instead of splitting the damage, you and your wearer combine your HP pools. When your combined HP would be reduced to 0, instead both of you are reduced to 1 and you are split back to your original form as per the original mechanic. You and your wearer are treated as one entity for the purposes of targeting, using the higher defenses among the two of you. You may also remove yourself at any time, taking up to your maximum HP with you and leaving the rest of the pool for your wielder/wearer.
Shapeshifting is cool and all, but a creative enough person can very easily exceed the bounds of the system with it. In our case, one of our party members had been considering doing this himself, but the idea for the actual feat came about as we were creating an NPC in a completely different campaign - where it was going to be someone’s Companion. (We haven’t playtested it yet to see if it’s busted…) The Symbiote Armor version was designed for the initial party member I mentioned, who is effectively playing a sentient ooze masquerading as a humanoid.
Please let me know if you have any feedback on this, especially in regards to balance.
