Mythical sword 15ed no sockets - would socket quest it to 3 and thinking maybe crescent?

Balrog blade 14 Ed 4 sockets - not oath cuz it’s not eth?

Phaseblade - 3os no Ed - crescent again?

Is myth or pb better for crescent?

crescent in the phaseblade is good weapon. lawbirnger too. i don't recommend using the mythical sword for anything. the BB could be made into a voice of reason for caster barb. you could make a passion with it. having zeal might have some use for a barb maybe. if you have more runes than you know what to do with you could make a hoj bb and have a holyfire barb. kingslayer makes a good iron golem.
