The Combat Assist Wen-Wen can be used while equipped in order to cast a proc nano on the user/wearer.
When used from a backpack, the Wen-Wen executes like most items, but then attempts to cast a nano on the user. This fails, and then locks the Wen-Wen.
Thus, the Wen-Wen gets locked for about 20 minutes, but the user has no benefit. Typically, items check to see if they are being worn when they are rightclicked. Also, they don’t execute and then lock-out if the use conditions aren’t met.
- Put Combat Assist Wen-Wen in a bag.
- Rightclick the Combat Assist Wen-Wen.
- Receive error message “You must be wearing this item to use it.”
- Notice your skill lock “First Aid skill is locked, able in 00:17:54”
