suggestion for the recombination mechanic

as of now the recombinator is extremely weak, all because of a single component: the success rate.

i would say boost the overall success rates but then it would break the balance and upgrades would be extremely fast (if the success rate is a lot higher)

what i suggest as a way to offset the values is the following:

create a bunch of new items that are expedition drops only (i would say from logbook expedition only but i don't know if it would be balanced) and then use those items only for the recombinator, it's effect will be something akin to a boost of success rate, there will be different tiers the same way there is different tiers of runes, each tier will have a set increase of success rate

here an example:

lowest tier [T1](the most common one to find, even outside of the logbook expedition) will give 5%

lower middle tier [T2] (a bit rarer than the T1) will give 10%

middle tier [T3] (overall rare drop akin to a high level gem) will give 15%

upper middle tier [T4] (a drop on the level of a divine orb) will give 30%

high tier [T5] (a drop extremely rare on the level of a headhunter drop) will give a whopping 50%


this is my idea on how to improve the recombinator
