There will be 2 types of requirement for all the equipment that exist in Black Prophecy.

The requirement are levels and stats. You might not have those godly stat, or you are focusing on just adding your stat on agi, int or what ever, you might not have that much stat for the requirement. Just go to the npc for lowering stats.

Stat
The requirement for equipment will of course as the game goes on.increase, and it will probably be like 60 maybe.
When you are going to get rid of the stat requirement, you have some options,
- decrease xxx stat by 1
- decrease xxx stat by 2
- decrease xxx stat by 3
- get rid of xxx stat once and for all.
Still, it is all by chances. The one hand bandit. The slot machine.

Once again, then the spinner for success or fail shows up. Hope for the best.

The level
You might just be able to use lvl 88(Black Prophecy Gold) godly yellow bow at the level of 1 if you are rich enough! so it must have something to do with the level lowing.
Same as the stat lowering, it is by chance, slot machine.. few option:
1. decrease level by 1
2. decrease level by 2
3. decrease level by 3 .. and that's all
but one thing that is different than the stat is.
When you fail to lower the level, the requirement goes back up!! but it will not exceed the original level though.

Blood line is another sort of buddy list, but the ranking requirement sometimes occur in some equipment. As usual, you can decrease the ranking by burning money.
