[@Champion] How's this?

I took some liberties with her abilities, since both [i]Darkvision[/i] and [i]Shadowmeld[/i] would be physiological traits of the Night Elf race, rather than being activated 'spells'.

Her [i]Shadowmeld[/i] would generally just be an ethereal mist surrounding Arwyn, she'd have to concentrate to make it solidify around her and so I counted it as a stamina skill, rather than a mana spell. With her [i]Darkvision[/i], I tried to give it an obvious setback, since it would also be something which would be constantly activated but which she could concentrate using her stamina to help to overcome.

As a comparison, here's the difference between [url=http://i13.servimg.com/u/f13/11/71/05/94/htmlco10.gif]'Human sight'[/url] and [url=https://i.imgur.com/KdwPqHS.png]Darkvision[/url].
