Legacy of the rose interaction

So here i'll talk about 3 skill version that the staff provides

first: shaper ball

i have noticed that the skill doesn't have base crit chance
the skill itself is kinda weird, it pierces all enemy but i've noticed that some isn't hit by the skill even though visually it is close to the enemy(which i presume they would be hit), i think this imply that the skill hit box is quite small, and the ball in the game is deceiving. (might be wrong on this one)

here are some supports that doesn't work, but it shows that it should work because i see that it has a tick when i hover over the support gem

first support gem is return projectile support, doesn't work
faster projectile support i don't think i notice a big difference but i might be wrong

sacrifice support, doesn't sacrifice life, and doens't deal any chaos damage as no life was sacrificed

these are the noticable ones that i tested, gmp , greater volley does work, and spell echo / faster casting does work as support gems

the skill pierces all targets, looks like this is fixed interaction, i can't modify even with snakepit where on wiki quoted "The projectile passes through the enemy after hitting it and continues along its previous trajectory. It is possible to disable "Projectiles Pierce all Targets" behaviour on skills via Snakepit, allowing a projectile to Fork/Chain/Return instead." the skill doesn't fork or chain with snakepit on, might be a bug or intended

second: shaper beam

scales with spell damage and damage overtime multiplier, nothing to say about this

third: shaper slam
can be supported by overextert support, but doesn't exert the attack
only tested that one, so other interaction might not work either
uses base crit on the weapon which is 8%, has 4100% damage effectiveness that cannot be evaded, honestly really really strong slam, but the entire skill is contingent on spending 200es per cast to get to 10 rememberance, since quoted on wiki" A single skill use can grant at most 1 Remembrance stack, even if 400+ ES was spent. Sacrificed energy shield is not count as spent.", so casting the slam might be slightly slower, but its like a jojo stand, so i think it is worth looking into, maybe cast when damage taken would do the job

these are my findings for now, some might be bugs or intended, but i think they are bugs
