I'm going off of the idea that conjuring an element takes a bit more effort than manipulating the ones that are already present.

Like, Didani can probably manipulate an entire forest-fire with her eyes closed, but conjuring such a blaze would be almost impossible for her. Strong mind and body, not so much of a soul (she has just enough to roll a +5 to intimidation, though), it's kinda one of those racial penalties of tieflings, actually. She's basically attending the school with what amounts to a supernatural disability, on top of leaving her equipment for compensating for it back at the dorm. So rather than admitting there's anything 'wrong' with her, she's trying to strength-train her tainted soul the hard way. At least that's how I'll rationalize it.

Also I realized at work that Xuno could probably pull a Thor and fly via swinging her mace, assuming she's got a stone or something in it.

Or, since she's got one hell of a strong soul, can just walk down a rainbow-road [i]if she'd have thought of that[/i]. Xuno would be great if she wasn't so dense.

The other two are pretty normal, I'm just not discussing those two because I feel like I need something to surprise you with.

...Fine, [i]one more spoiler[/i]: Lilith will be loading her crossbow with literal ice-bolts that'll shatter (going to flip a coin on whether on impact or airburst) into a fine mist of ice-crystals.
