Thank you for the very detailed reply regarding Ultrax; I didn't get to see it in my initial scouting of Shettera. I have 5 AK scrolls left, for a total of 25 enemies:
5 at Tekron (4 heroes, 1 regular)
13 at Shettera (5 heroes, 5 regular, 3 dragon-regular)
2 at Dersu (2 bosses)
4 at Nameless (4 heroes)
1 for Baal
I will start suppressing items in between AK chain-fighings.
I'm halfway through level 55 right now; hopefully the above battles and quest experience would get me to level 60.
Unfortunately, no sooner had my contracted project ended (Friday last week), and here's a call for another project to start Monday next week (and would last till mid-July).
Sigh... I guess I should be happy for the steady stream of work, especially in this economy. Maybe I could sneak in some playing time this week while preparing for that project...
