Hi, I’m new here, so may be i wasn’t able to find anwer because i don’t know where to search.
I stuck on Doom Glade level in Blackwoods Forest and after two head-on attempts to fight oges with my knight having 844 life, i decided to use alternative strategies, for example flag-mining, but it failed too.
Is there some special strategy for this level or I should return here after completing further levels in further worlds? With some advanced knowledge and abilities?
Looks like I really don’t understand how I need to use flags to win this level.
Do I need special strategy or advanced gear/abilities/knowledge?
Possibly… 
Hmm, I believe the ideas I used are introduced in the desert…
I didn’t attack the big ogres, I attacked the ranged units first and let the soldiers kill the biggun’s.
My strategy was to use omarn to pick off the ogres and shamans mainly the shamans
I definetely can’t survive a fight like this now.
So i’ll get back to this level after desert with new gear/abilities.
Thanks for all answers.
