If i was you i'd grab some garms and head for the dark ravine. Since you cant kill mobs your own level, try for some below your level.
In dead ravine the mobs use osme magical attacks where garms coupled with your already high mag defense means u will die less.
They also drop wind 2 which comes in handy

(or maybe it was wind 4, cant remember)
If worse comes to worse, use cold imbue. Makes a huge difference.
