User blog comment:ClariS/Nalis, the Scarlet Cardinal/@comment-5015210-20121207142417

Her E looks like it has too much utility. I recommend changing it to something like this: Nalis dashes in a straight line dealing damage. She leaves a wall of bloody crystal behind her that looks cool and blocks enemy movement. Enemies 'hit' by the wall are slowed.

To make it more fair the dash range is fixed, hence the slow. You can also add some other effect related to the wall, like: making it passable but enemies who walk over it have Crimson debuff applied to them or something else.
