I have both Ebenruth's Nol and a yellow 3.1% speed crystal it feels a little bad having to give up stats to use a treasure item so lemme consume the speed crystal in a one time use type of deal to put its stats onto Ebenruth's Nol in addition to the existing Nol ability plz. Something akin to an accessory cup/vells heart upgrade/Garmoth's Heart item reform

bad pirate. bad.

+1 for suggestion.

Your suggestion is something i had in mind but for cristals. Nol is already super powerful and hidden behind some crazy rng (or some hard bartering). But allowing it in the process would make some content for players like you. 

Dropping many crappy yellows, i was begging for a system that would allow your cristal to grow:
You get an empty cristal with 0 stats and you fuse it with the stats you drop from other. A bit like VELL boost on DP.
And each time you add a colored cristal... it gets 0.1 on the stat you added.
example: it would take 10 yellows to max up one stat. that's already a lot of grind.

Atm, only speed and weight are used. Even monster damage is too low. Would be interesting. to have a system where at the end you get something nice depending on your effort, and not your luck.

Same system could be applied to sailors. Been leveling innocents for almost 4 years... never had a 4.0 and never saw more than that.
having your sailors level up when killing monsters even when level10 would be nice. Everything is rng. So it's get loot... and get lucky or get fucked because it's totally useless.

he is indeed, a very bad pirate.
i will agree with your +1 and say this would be a very good idea would make it more fun killing sea monsters with a NOL imbued with extra monster damage
