Stuck at the last monster in the Labyrinth of Malufus

I can't kill the horrible group of monster in the last third part at the Labyrinth of Malufus.
I don't have any member in my party this time. It's only me (Random) all monsters keep hitting me.
I don't even have a chance to use item to increase my HP.
Please help & give me some tricks.
