Here is the part where I embarrass myself once again by entering a tournament with full intention to see it through and then abandon it long before Nightmare.
My assassin is named Phusis and she intends to be a Phoenix Striker later in life (frozzzen and nagi keep talking about them, and Jian keeps extolling them at high decibels, and so fourth). At the moment, I am pumping the charged bolt sentry as a leveling strategy, but it is not high enough to be of any real help.
I have found two S/U items -- but neither from monsters! The first was the Pelta Lunata, which dropped from the chest in the Mausoleum/Crypt. The second was Bloodfist gloves, which was exactly the fourth item this character gambled. I was, needless to say, rather shocked.
I am wearing 4x chipped topazes; my merc is doing likewise.
Phusis the Assassin, level 16, 2 S/U items equipped, Outer Cloister next
