While I do really like this lost technique, it feels a little upsetting knowing only strength builds get something like that for now.
Here is my suggestion: Add a spell and spirit rite similar to this .
Transformation
Spell: Transformation
This spell allows the player to use various stages in order to change their apperance and stats.
Amount: Changes the amount of stages, more lifetime and lower per-stage potency at 9 stages, and lower lifetime but lower overall potency at 3 stages.(slight cooldown decrease with each stage added as well)
Size: Scale from 1.2x to 2.5x character size(at stage 9). Size will naturally progress to this point with each stage. At max size, you are granted higher defense(plus slight potency buff to the mode), however reduces agility and increased energy+stamina costs on all attacks and dashes/t jumps by around 10-20% at max.(please note character size will only affect the particles if it is something like the Aura shape)
Shape: Many shapes will be available, and will give you new M1s.(note to devs- it is okay if you dont add the animal transformations)
Samurai: yes, this is basically just Susanoo from naruto. Will come with a crossbow and Katana variant.
Bear: Why not? lets you claw people a few times before charging as your M1s.(yes, bears can stand so 90% of your spell animations will in fact stay lol)
Aura: An aura will form around you with every stage. At stage 3 or higher, you begin to hover over the ground and your M1s will gain double range and gain some terrain piercing.
Armor: You will gain a shell of magic around your body, which will be similar to Jarl Ivar’s. Your M1s will make you slam your
fist into the ground
Mutilate
Use spirit energy to mutilate your body into forms in order to attack and buff yourself.(yes, this is inspired by Mahito and spirit energy can in some way affect the shape of people’s bodies from what ive heard)
Stage 1: Turn you arm into a blade and slash a large area ahead of you, then revert the change and gain an aura of spirit energy along with some deformations, granting you a damage boost while reducing your blocking power.
**Stage 2:**Transform your arms into flails, spinning wildly to create a whirlwind around you. After turning your arms back to something close to normal, the aura intensifies and you gain extra attack size. You also deform a little more, and now have a slight drawback to your attacks.
Stage 3: Turn into a deformed, enlarged version of yourself and release a large amount of spirit energy around you. The aura intensefies even further, increasing size, damage, and defense. The transformations have caused damage to your body, increasing the drawback of your attacks, reducing your agility, reducing blocking power, and dealing 50 damage every 7 seconds.
