Do essences make an item magical?

[afreshstart]

Can I put a permanent essence on a bronze item and then cast GMW on it?

[cptcuddlepants]

Nope. A permanent essence will block GMW.

I found this out the hard way

Thanks! And I'm sorry for your lost bronze weapon.

I think You can do GMW -> Enchant in Basin with 1d4 AND add Essence on top of it...

Though it is prohibitively expensive for a single use weapon - better go Fighter
