Two players for The Price of Immortality - Best debt collector?

[Morganstern]

So, due to one player no longer being available and another not having a vehicle anymore, our party of 4 is now a party of 2. The other player is playing a neutral cleric that's focused on channeling and casting (versatile channeling) with some combat ability, and my paladin died soloing the boss room at the end of Crypt of the Everflame. The GM is letting me come in at 3rd level, and with an extra 7,000 Gp to spend to help offset the lack of players (cleric got the extra cash too). Any ideas on what to make?

Edit: stats are rolled as 2d6+6, I got 18,18,16,15,12,11.

Gish. Magus, Hellknight Signifier, or Eldritch Knight. Gives you the ability to survive without the frontline and lets you keep arcane utility. Its a bit Mad but you do have the stats for it. Int=Str>Dex>Con>Wis>Cha

Summoner seems like the best to cover your holes. It crushes in melee, boosts your action economy, can fill in your missing skills (Eidolons get good skill points beyond their HD deficiency, which is only going to be 1 at most for that trilogy's level range) and offers some arcane utility.

Ranger with longbow and animal companion. Favored enemy = undead.

I second Eldritch Knight and Summoner as options. Summoner is raw combat power while EK is more versatile and brings more utility to the table with 9th-level spells.
