As we all know, the original user of this technique was a monumental bum, to the point that even Gojo himself had to make it clear that his cursed technique had potential, but its user was just kind of a loser. So I have taken it upon myself to expand on what I think is a logical progression of how this technique could develop and evolve in the hands of an 'honoured one-type character'.

~Cloning Technique:

This technique allows the user to clone themselves using a mud-like liquid manipulated with their cursed energy. The user can produce up to four clones, for a total of five bodies, and swap their real body for a clone at any time. Every clone is identical to its original caster. A new clone cannot be created immediately after a clone is destroyed. [Taken from wiki]

~Extension Technique – Ranged Recall

This technique is only possible through a pair of highly difficult binding vows. These binding vows are as follows. One increases the 'cooldown' period between clone productions when a clone is destroyed by an outside source, and the other is a life-sacrificing binding vow that instantly destroys the clone. In return for these constraints, a clone may be resummoned at a drastically reduced cooldown, even when significantly injured. This allows the sorcerer to rapidly reposition their clones in real-time combat to create unexpected attacks or retreat quickly.

~Technique Reversal – Fusion

Reversing this technique allows multiple clone bodies to be fused into a single form. It can also be used on the sorcerer’s ‘real body’ to fuse any number of clones into it. In either case, the resulting body gains the combined might of all fused clones across all categories, from strength and speed to talent and brainpower. Some of these combined characteristics ‘scale’ better than others, and some may have ‘soft’ caps on their combined growth, so a simple 1+1 might not always result in 2, but could yield 1.5x or 3x the effect.

~Extension Technique – Cicada Sheds Shell

Using this technique allows the sorcerer to transfer any and all negative conditions onto his clone (short of complete annihilation). This technique can be used during fusion to forcibly eject a body, along with any injuries or status effects it might have, while retaining all positive traits it possesses at that moment. Through this technique, the sorcerer effectively has 4 extra lives while in a fully fused form with all of his clones.

~Imaginary/Compound Technique – Egocentric Lifeform

This technique is essentially an exploit of the system by which clones are ‘made’. By fusing 1 ‘clone body’ with the ‘true body’, the sorcerer will gain the strength of two bodies. The sorcerer must then create a new clone – but the technique's strength lies in the fact that this new clone will have the strength of 2 bodies, as it is an ‘identical’ copy of the original. This exploitation can be repeated until the sorcerer reaches their cap of 5 clone bodies, adding 2+2 for the 2nd clone, then 4+4 for the 3rd, until finally gaining the strength of 16x themselves by adding 8+8 upon fusing with the fourth. This technique is inherently unstable, however, and requires extreme skill and bodily control to contain such power, in addition to large amounts of cursed energy to create and maintain such powerful clone bodies.

~Domain Expansion: Proof of Existence

This domain uses the sorcerer's soul as a barrier and therefore can only affect the sorcerer; coincidentally, it lacks a sure-hit effect as well. In return for these conditions, this Domain Expansion is incredibly cheap to use. The effect of this domain is to grant any clone the property of being the 'true body'. This means that another sorcerer must exercise every clone before another can be created for the CT user to truly be killed. In addition, this relaxes other restrictions, e.g. how far the clones can go from the 'true body'. In return for a constant drain of cursed energy, this domain expansion can be used to create up to 5 ‘true bodies’

Feel free to tell me what you think of my ideas and add on any ideas you personally have.

Ok, so I've been fixated on seance technique for a little bit because of a random character-building challenge.
My question is this: would seance technique allow you to use a dead sorcerer's cursed energy trait?
My general understanding is that the technique could be used in a similar manner to the soul switch training we saw at the end of the series, where you gain access to the body's muscle memory and can learn techniques from it, but what about cursed energy itself?
Would that count as part of the 'body' information that you summon using the technique?
