• I have a thorns 2 book (will be using for diamond chest plate) *I have a infinity power 4 unbreaking 3 bow
• I found a book with thorns 2 and power 4 I’m gonna put thorns on my diamond chest plate but the question is, do I use the double enchanted book to get thorns 2 on my leggings or do I use the book to get power 4 on my bow which will then be power 5,unbreaking 3, infinity

I’m thinking about using thorns cuz my bow is on full durability and I’m planning to use an anvil to repair and at the same time get a enchant (power 4) but it will take a long long time for my bo to get low durability.
