Up to yesterday, with UOAssist, you would have to open the belt before it worked (could close it), which was a real pain to find in an emergency if you forgot to do upon ressing. The belt no longer has to be opened before use.
i use a macro in CC, for bandage nearest follower & as Norry said... you have to have the first aid belt open and target the pet with a bandage, before i can use a bandage on my pet. That is using CC without UOAssist...
now in EC, with Pinco's all i have to do is, open first aid belt, drag the bandages into my F1 slot. Then any time i want to bandage my pet, i just hit that key. I DON"T have to have the belt open again. (it worked like this without Pinco's too)
because it works better in EC, i tend to play that client, because i hate having to reopen the first aid belt every time i die...
