Even though there are two more floors in the dungeon, 5F is effectively the last. You'll likely come here first in the three Treasure areas, but the main entrance leads to a save point. Make use of it, because there will be a boss fight shortly after.
The Magus Sisters are, like Baigan, annoying because your primary target of three has Reflect. Killing Sandy or Mindy is pointless, since Cindy will just revive them. Magic won't work very well, nor will Bersk. Just concentrate physical attacks on Cindy (the middle one), and put up Shell to help guard against their Delta Attack. This fight can be long, but it's not that hard if you know what you have to do.
There is another boss fight coming up, so you may want to return to the save point. Further, Tellah is about to leave the party, so if you want to keep his gear (especially the Change Rod and Wizard Robe), now is the time to disarm him.
