Concerned With Party Composition

[Toade]

As stated in title! Our party going into this is down an individual, so we are merely 3. The other two have locked into swashbuckler and Undead bloodline sorcerer with a focus on summoning undead. I had originally thought to go Starlit Span imaginary weapon, but with only 1 frontliner, that seems a bad idea. Similarly, we don't really have a skill monkey character in the group, or a heavy tank... With the two listed, any recommendations on what to do for the third to try and cover the group as best as possible?

For an extra support you could have a "minon" NPC for the Sorcerer? Some Undead that is attached to him in some way? That could fit the heavy tank role.

Our group has an Investigator with Alchemy as his Free Archtype. He is highly versatile as a skill monkey and is a great healer.
