What do I do at lvl 27? I need to be level 29 to continue with the storyline.
is the prepare for counterattack the one where you fight 3 slingshot bosses at once? quite a problem for evys tho :O
Grind it out. Go AP farm the battles that still give more than 10 AP, before you know it you will hit 29.
According to my guildie, he got 27k XP a run soloing Counterattack Macha...
As said above I got around 11k on Ulchas with Macha of OoA each round consisting 8 minutes. I ran kobold chief awhile back. (maybe like..level 22?) And i got over 10k exp from it. Though I'd follow what Ruquion said! :)
