Teleporter (50%)
Twilight pulled out her teleportation tablet, with some caution as she remembered what happened the last time she used it. She concentrated on her desired location, on top of the museum roof, and poured her magic into the tablet.
With a sharp snap of magic, she found herself floating in midair, before falling. She fell about a meter before landing on the rooftop. Of all the things that could have gone wrong, this was definitely one of the more preferable outcomes.
Now she just had to enter the building. The maintenance door she had seen had a single Unicorn guard posted outside of it. They should be easy enough to deal with.
Bit
Tranquilizer
Flacon Punch
Invisibility Pill
I vote for the Invisibility Pill, AND THEN the Bit. So that we can have at least one fail before the right one - the fail that WOULDN'T get her caught too quickly.
Falcon Punch
