1) I've not tried any daedric quests yet but I wish to start some of them now. Has OOO changed the level requirements from vanilla and also, presumably the difficulty has been increased. Is there a list anywhere of level guidelines for the deadric quests when using OOO?
2) Are oblivion gates of a fixed difficulty or do they scale in some way with OOO ? Are the creatures that lurk outside the gate an indicator of the difficulty inside? So far I've done the Kvatch part of the MQ but struggled at the time. I'm higher level now but still tend to get whipped by a clanfear thats guarding a gate. I'd like to try closing some more but don't want to get my ass kicked

3) I keep reading how hard Umbra is in OOO but nobody has clarified quite how hard. Any ideas on a sensible level to attempt this?
Thanks.
