Sinbad is in a similar level of trascendence but his ability to change trascendence is better than most of Rimuru abilities, he also is protected by Higher D beings, that resurrect him, like when he lose his indivduality against Ugo and he moved his soul to the soul cycle. But idk much about EoS Rimuru, this is from what i know.
Rimuru easily crushes, after he gets dl transformation, he gets all status immunity (fire, shock, poison, sound, etc). On top of that time and reality manipulation. Also btw his auto battle can automatically take over if he is under mind control. His skills are able to overpower those of sinbad and negate them. And how many times do I have to say MAGOI IS NOT THE SAME AS MAGICULES THEY CANNOT ALTER EACH OTHERS MAGIC
