infinity tower summoner

[Kixtar]

2 things rq. Any summoner with new offal skill have video of it in use? I want it but it is expensive. Also, Any floor 55avg+ summoner give me a list of your soulshield, how much crit defense to shoot for etc? I saw some interesting asura/challenger builds but it was pieces of Asura I wouldnt normally use for PVE, so just curious what SS you all use. Also any general tips would be appreciated. I have 74 tower entries and want to grind xp here now soon. Thanks!
