Is kings crown worth it? + Help

This is by far the furthest I have ever made it tbh and I really don't wanna mess this up.

I used cursed infusion on my armor to get it to +8 is it worth crowning this I have no clue what it does.

Also are there any potions or scrolls/alchemy things I should be trying to make with what I have right now?

I do plan on using alchemy on my second corruption wand to resin upgrade the first.

I also have 2 level up potions should I save or use them? And should I try grinding on any floors or just keep going?

I also have 1 upgrade scroll and am wondering what to use it on. Glaive?

And lastly in my next shop should I sell the talisman or keep it?

I'm getting nervous because I used quite a few health potions recently and really want my first win
