How can DNF strengthen 100% success?

Enhanced coupons are below+10, and high-tech coupons are above+10. If you don't use it, you can only "improve" the success rate as much as possible through the knife pad method. Specific tool patching method: it is wasteful not to patch the tool below 10. 1 1 on1doesn't need a mat knife, and two 12 mats will break. On 13, more than three mats will be broken (even broken)+13. As for the upward reinforcement,+13 cushion will be needed. The specific number of broken pads will increase with the increase of reinforcement level. This is what one of my classmates in the blade master told me. I hope it helps you.
