I like that you are showing the previous lower tier versions of the spell even tho he's not going to use them even once, it feels satisfying looking at how much the skills/equipment grows
Honestly, i dont like how synthesis was no different from lottery(that you wont lose). I would pretty much prefer sythesis that combine the ingredients properties and not generate some random item of the same classification. I would also recommend adding classification to each tier-both skill and Item (Like A+, A++, or A-). It would also be nice to add some lore to the items. (decayed staff > Wooden staff and so on without diverging from the base name or item) In any case, this was just my opinion and things i do like when reading some fantasy stories, i don't like too much exaggeration and things that is over the top without any context like how he easily get S class item and skill and how as if he already know what to do... I see for myself if this is worth my while
