Wamphyri

You can put the file below (wamphyri_mount_modifier.png) in the effect asset folder for your mudlet profile to get a buff icon for your Wamp mount boost. For windows 10 users that folder is in users\<name>\.config\mudlet\profiles\Midnight Sun 2\MS-GUI\images\effects.

The mud already passes through a variable for that buff, the only thing that's missing is the image file with the proper name to load. (That's why you see the blank slot in your buff row when you're mounted.)

You can also make your own 42x42 pixel png with the 2 pixel black border.. but the one provided is hilariously bad (it's snipped from a picture of a Halloween decoration) so I'm not sure why you wouldn't want to use it.
