1. I think that if you play trapsin you will benefit more from a headgear with + skills, as Harlequin Crest, Delirium (rune word) or at least a rare circelet (you can gmble for them or use CharsiÂ´s quest to inbue a white one). If you donÂ´t need resists and MUST use GuiliameÂ´s face - lightning facet wouldnÂ´t be that stupid for LC.
2. In Pit you can have some problems with lightning immune archers (corrupted rouges or something - not skellys - the latters are immune to cold only). Their packs are not that big so with good block rate, some kicks and - may be - one point in MB you can surely persuade them to be nice girls.
