I've been playing with Morph Brokerage and Resleeving using the Fate system. Morph brokerage and Resleeving can be as many as 5 rolls in EP core. I pared that back to 3, but it could probably go down to 2. Here are my notes.
When a player wants to purchase a new morph, they perform morph brokerage. To perform morph brokerage, the player rolls their Networking skill vs the cost of the morph +/- modifiers. The results of the test determine the type of morph below. Fail - Player could not find a morph of the desired type. The GM may offer any Morph aspect in it’s place. Tie - Player finds a morph of the desired type, but the GM may phrase the final Morph aspect. Success - Player finds a morph of the desired type and may phrase final Morph aspect, although the GM may offer a slight tweak to the final phrasing. Success with Style - Player gets complete control over Morph aspect phrasing and a boost to use on purchasing or integrating with the morph. After the player finds the desired morph, they must still purchase it. The player rolls Networking or Resources vs Morph Cost +/- modifiers. The player may reduce the Morph Cost by their current Morph Value - 1 if trading in their previous morph. Succeed or fail, the character ends up with the new morph. Any shifts of failure are applied to the Wealth or appropriate Rep network stress track. After the player has purchased the morph, they must then integrate with the morph. The player rolls Somatics test vs the Integration difficulty of the morph listed below. Base integration difficulty = 1 Character has sleeved in this Morph before -2 Character has sleeved in a similar Morph type before -1 Character has not resleeved before +1 Morph is different gender than what character associates with +1 Morph is synthetic +1 Morph is heavily modified +1 Morph is significantly different from what they are used to (uplift, infomorph, Swarmanoid, etc) +2 Consult the following table for result of integration test Fail - Character has -1 to all actions until the end of the the session. Tie - Character has -1 to all actions until the end of the next scene. Succeed - Character has -1 to all actions until the end of the current scene. Succeed with Style - No ill effects, character gets a free boost to use on their alienation test. Finally, a character must make an alienation test using Will vs the previous integration difficulty + any modifiers on the following table and take any unmet shifts in composure stress. For each physical consequence on your previous morph +1 You died +1 Short break in continuity +1 Large break in continuity +2 You are a fork +1 Not knowing how/if you died +1 When a character is resleeved, all physical consequences associated with that morph are erased, however any social or mental consequences remain.
