Late last night I managed to do the spawn in Deceit w/o dying for the first time. Then first thing this morning I manage Rikktor without dying. I don't know the exact time, but the undead spawn took me just under an hour. I did look at the time for Rikktor. From the time I recalled to the outside of the dungeon until I was back at the bank was 51 minutes. The spawn itself took about 35 minutes from when I dropped valor on the idol to start it, until Rikktor popped. Then a took another 2-3 minutes to clear myself a place to maneuver while fighting Rikktor, Rikktor himself took me about 6 minutes. Then it took me about 5 minutes to clean up loot. Now if only I would have gotten any useful scrolls out of these spawns. I think I've now done 4 or 5 straight without getting any 120s.
