You can teleport to a spot nearby. It looks real cool because you disappear in a puff of smoke (or a flash of light, whatever you want). You must be able to see something of your destination, but you may ignore any intervening pits, transparent barriers, people etc. The difficulty of this check is 5, with penalties for Cover and Range.
A failed teleport means you materialize somewhere bad.
Blinking is a 1-shot action that costs an Magic point. It can be used as an active defence, giving you a +5 bonus to Dodge, and also gives you a limited surprise when you arrive; your first action after teleporting gets a +3 action value bonus on any opposed test where surprise would be an advantage.
Shelly the Unicorn is trying to teleport behind a nearby couch. The difficulty is 5, plus the couch almost completely conceals the area behind it. This increased the difficulty by 5, to 10.
