Forgotten Tales

I had been playing forgotten tales before. When I had realized at L96 that the Princess Resa quest is necessary to get the map from the hermit. So I started all over again. Now at L75 I (stupid) saved the game (all three slots) though my archer had died.
Does it make sense to go on or is the archer needed or even essetial.
Thanks for your answers.

Honestly you could go on without archer, aside from a little extra dps you don't lose much. In terms of the RPG mode the archer is 2nd to last worse character due to it's low hp compare to others. This is just my opinion thou.

Thx! I just wondered, because 1/4 of "non-magic-fighting-power" is lost.
