Fusion Dance

You have undergone extensive dancing training to gain the ability to perform the fusion dance. In order to perform the fusion dance, a second creature must also have this feat and must be willing to fuse. If both creatures are within 10ft of each other, they may spend 1 minute repeatedly using their actions and concentrating to dance and chant. Once completed, they combine their bodies and souls. The combined resulting body will appear somewhere within 15ft of either caster, agreed to by both users, and have the following properties:

• The body will generally retain any positive benefits of both bodies, replacing worse properties with the better of the two bodies. For example, if one body has a flight speed, the new body will too.
• All ability scores from the two will be combined to a maximum of 60. HP and temp HP are combined.
• Each user's proficiencies are added. If both users share a proficiency, it becomes expertise.
• Spell slots from each body are combined, such that if both have one 3rd-level spell slot, the new body would have two.
• The two users must decide which class between the two users for the new body to have, not both.
• The users' inventories and currently worn equipment will be combined, however, they may agree to drop however many items they wish.
• The fusion has six attunement slots, and magic items previously attuned by either party will instantly attune to the new fusion.
• The user's proficiency bonus will not change.

The two users must decide on what actions their fusion takes, if they cannot agree, the fusion takes the dodge action. After 1 minute or dropping to zero HP, the new body will defuse, causing the two original users to appear somewhere they choose within 10 feet. The two users will be in the exact same condition they were in before the fusion, however, they will be unable to fuse again for 1 week.
