Looks like nobody answered your question, maybe someone PM'd you and gave advice.
There really is no Best Solo build for farming... it is all gear related. However, you may not like dropping into a Trap Door, so the best feeder would be a Rogue since it can detect trap doors.
The Rogue is universal, so it can use all the best weapon choices and use armor class upto Scale (not chain or plate being heavy). You start of with high dexterity, so Dagger or Axe is open, you can also use EE staves if you do not have the funds until you find your ideal weapons. Rogue has decent Intelligence, but pretty low on Vitality, so you will pump vitality early.
You will need to choose your Abilities as best you can.
The typical setup for weapon, armor & main charm for a melee Rogue is EE for Wpn & Armor and Stat for main charm. You can use an Enhanced Effect heal charm in ACC if you want.
Simple as a normal build, the only difference is that a Rogue can detect Trap Doors and you can explore the entire catacomb.
