Hello!
I’m not sure if Miqo has a built in thing for it yet but back when i had to fish blue crabs, you didn’t want to go over 10 seconds because it would mean that it was NOT a blue crab so someone in this forum posted this below:
/micon “Cast”
/ac “Cast” <wait.10>
/ac “Hook”
I would give credit but i have no idea who posted it but you could probably do the same thing.
Replace the normal cast key with a cast macro listed above and replace the <wait.x> to whatever you want.
In your case you probably want <wait.20>.
If someone else has a better reply feel free to jump in!
