I know this idea has been difficult to implement in this setting, but I would be very keen to get one working. I have a few ideas.
1) Use it similarly to Focus boosting an Ability: you would increase certain physical/mental attributes of your character, but only for one scene, and it would consume Focus to do so. It would be somewhat a 'soft' upgrade, where it allows you to hit harder, tank better, move faster, etc. but without putting exact numbers on it. Once the scene is over, it's gone. It could also be changed to consume more Focus (maybe 2 or 3) in a scene since it improves on multiple attributes at once.
2) Have it be a Consumable: it could be similar to a Revival Consumable, where you can only have one at a time, and it has a decent cost (not too big but not small either). Perhaps there could be ranks in this system, where you get a greater boost (maybe Basic, Moderate, Advanced?) but it costs more for each one. You could include a cooldown so that it takes longer to purchase the more powerful boost again than the mid or basic one.
3) Build a transformation: using Essence, you purchase a Transformation Ability, which you can then add Effects to (Damage, Speed, etc.) You could have a separate cap for the number of Ranks an Effect could have in a Transformation, much like there is a cap for them now. I'd see it as being a blanket improvement on Abilities that have the same Effect that is in the Transformation. You could, say, buy a Damage+1 to your existing Abilities, but the cost of Damage would be higher (eg. 300 per rank, maybe more?) It could also consume Essence to use and have cooldowns involved.
Happy to discuss if any of these ideas are possible or what would need to be done to rework them into something viable.
