What should I do with the implicit modifier of a unique item?

I have this beauty:



Very soon I will 6-link it (have around 1200 fusings). My question is what should I do with that 30% increased acc rating, because I can't miss anyway (passiv tree keystone). Vaaling it very risky and only the the +1 weapon range would be good anyway (about 5% chance?).

I probably want to corrupt it to 30% quality and maybe modify skill tree to go accuracy(?).

This is my first league, I don't know everything about the game and would be grateful for any help.
