In solo edition, moloch normal is easier than that all:
Equip a rogue properly
crafted death eth bow ( the best you can do ) works fine, if not, go on vidalas for the ctc amp ( no, thats not for you, you will do nothing ), try to max and sox the equip so she gets a cute dmg ( jewels with +x to max dmg works good )
Be sure that when spawning Moloch, your rogue is far away from his hateful psn dmg and carrion vines, I will upload some "paint rage selfmade icons" to show you ^^.
Lure him into you, remember to walk with your holy shield always on =). Equip death gloves. If you dont have good rare/crafted armor and helm to sox em, equip sigon armor and helm, and put 3 x perfect diamonds on both.
If you are lvl 55 ( I doubt that ), go on 3 x SS diamonds .
Stay infront of him, and let your rogue kill. do
nothing except assisting with aura and healing your rogue and yourself with pots constantly. Since mercs do full dmg to bosses on single player ( its like they pierce all kind of resistances... somehow weird and OP ), the fight wont last more than 2 minutes.
No risk at all, but if you are bored, go smite a lil bit
