Joachim here, checking in to EnWorld for the first time in years it seems. Looking forward to this campaign more than most because it looks to have a deep well of RP possibilities. Kelvin is my PC. Good to see some familiar names still posting in support of JD's good work!
Not Jollydoc, but I can answer your questions from a player perspective...
I will admit that the the Saventh-Yhi portions of the module have been less than exciting to this point. A bunch of disjointed encounter areas (without so much as even encounter maps) with little to do with each other...
I like how in the story we were the aggressors with the druid and her pet dinosaur, when in reality we just ignored her and she attacked us. Never let the facts get in the way of a good story, eh? ;)
+1 to what WarEagleMage said.
Age of Worms was fun, but the random monsters that Jacobs came up with that had random abilities (see: immunities) because very tiresome. Punking Dragotha was effing epic.
Savage Tides...what can I say? Brilliant execution.
Rise of the Runelords...the lamia...
And here is Velox...I am impressed with the Battle Oracle. He can kick some ass. If I could go back and do it again, he would have taken the heavy flail instead of the greatsword, so I could use trip maneuvers with it.
Here is a .pdf of Arioch's character sheet, at 2nd level (we made it to 3rd as of last night).
Couple of notes on feats....JD lets us take a bonus feat at 1st if we participate in the Crit/Fumble decks (which Paizo has recently released as iPhone apps I might add), and we also use the Hero...
Current Serpent's Skull PC's and their Kingmaker characters:
Master Summoner - Velox (me)
Undead Lord Cleric - Davrim
Barbarian - Selena
Alchemist - Tungdill
Arcane Duelist Bard - Stevhan
Hexblade Magus - Mox
I really like the summoning aspect of the summoner, and have never really liked...
