Merlin wavered a hand. "My capabilities are somewhat in flux, but- I was originally a prophet. Sadly that side of myself is less reliable these days. But as to what else I can do- A lot, is the short answer. The long answer: Shape-shifting, climate control, summoning spells, defensive spells, combat spells, sleep spells, sometimes telepathy..." He took a deep breath and held out his hands in front of him. "Some of it is more exhausting than others, for instance affecting the weather is not something I like to do often. I can imbue objects with power too. I could have this whole apartment packed into a duffle bag in four minutes."
