A question about equip requirements

You can use a MW cast to start a chain though. For example, if you have 100 base dex and two different items that require 120 dex and add 10 dex, you can't equip them normally, but if you get 19+ MW casted on you, you will be able to equip them and keep them on even after MW expires.

Not sure what you mean.

I tried this with my Ele Staff, which requires 105 Luk. I put in equips until had 104 Luk, since my Ele Staff has 1 Luk on it. With MW, I could equip it. Then when I right clicked MW, it turned red.

Do you need 2 items to pull it off?
