(OOC: Sounds good to me. Hogarth is Acid. Nurlan is Fire? Cold? I don't really know anything about Nurlan)
*Her protections ready, Ashna strides down the stairs ahead of the rest in order to cut off Line of Effect with a Wall of Ice. In order to have line of effect to the spot for the Wall of Ice to be placed in a relevant spot (that is, beyond the edge of the safe area), Ashna will need to expose herself to Sin and friends as well. As she rounds the corner, she sees that some of Sin's Wraiths are standing quite close to the edge of the Crux's emanations. This is not good as far as placement goes, since if she places it farther out, some of the bad guys, including Sin herself, will be on the PCs' side of the wall, thus making it useless, if she places it closer in, it will be in the safe zone, thus boxing the PCs in and hindering them more than helping, and if she places it right on top of the Wraiths it automatically fails (if adjacent, they can make a Reflex save to screw it up too). Ashna gets the feeling that she did not win initiative, but the enemies seem content to let her make the first move.*
(OOC: Ashna's turn)
