Quick and Easy Questions (please read the OP)

I was looking through the rules to see which Powers even mention an energy drain and they are as follows:

Flight, Burst Movement, Disassemble, Phasing, Teleportation, and Time Manipulation.

Generally speaking, you should be using the information, including energy drain or other weaknesses, as a guide when making Moves which build on your Powers. Ignoring the drawbacks of a Power when building a Move that uses it is tantamount to trying to circumvent the balancing of that Power. If you, say, made a Burst Movement Move that allowed you to rapid fire quick jukes and dashes for no energy drain, it'd be unbalanced.

However, in Viola's case, I haven't seen an instance yet of her really doing so. The Power specifically mentions that speeding or slowing time is what requires a great deal of effort, and the only Move that I've seen so far that does this is her "Haste" Move which (I think) is still in Approval. And was nerfed to require an energy drain on the level of that the Power requires. The rest of her TM Moves do other things in regards to the Power that weren't specified in the description for the Power, so the energy drain requirement is a little looser.
