Is there anything valuable among all those items?

the last amber aegis will be a few arm (dual ench)

maybe ornate shield q9 +1/20 illu -3 hex few ectos

that's about it imo i would trash the rest

I'd throw 10e at the echo -desease -2stance, so dont merch that one

first echoval is 1-10a range imo the others you can trash
