Bonus Book of Melding - You have to click the Bonus Book to get either +1, +2, or +3. This Bounty Bay gold is used in conjunction with a cover, eg. weapons cover, or gang suit. The max effect is +15. Because it is covered, you can not use a PRS on it.

But you can upgrade with it. I was sleepy and upgraded a covered +12 weapon twice. What eventually happened is that my weapon went from +12 to +14 after the cover wore off.

Now when I upgrade I take ALL items off. I could have failed a broke my weapon too, but was lucky. You can not show, trade, or sell any item with the Bonus Book of Meld on it.

You have to buy a Bonus Book of Unmeld to take the cover off in case you level early or need to sell your armor or weapon. Effects last 30 days in which the item goes to its original state. The bonus book of melding + is also lost.

Original Bonus Book of Melding is trade able. Once you identify or click Bonus Book of Melding showing the +, then it is NOT trade able

Note: I tried to upgrade once a weapon that was +9 with a +3 cover. I used the RoP II. The weapon broke and went to +10 totals.
