I have no bubble as I pimped my Igni first. Honestly it's tough! I have to dodge or roll with perfect timings or I'm in trouble! Also I can't go into a bigger fight without gearing up with the right potions and bombs. Simply I have to use all available tools just to survive, especially when fighting similar level packs of monsters, like drowners or higher level single opponents. But it's really good fun when after long fight you're left with no bombs at all, barely any life left and full toxicity so can't even heal yourself with potions! Afterwards I always try to hunt rabbits / deer to get some meat and boost my health again
BTW my Quen now can take two hits from lesser monsters before protection is gone!!
PS. I'm amazed how good some of the monsters are done! I love Foglets as you can see how they move in the fog when invisible by they way fog is disturbed! They are tough to defeat, especially when fighting 2 or 3 at the same time ...
