I just finished converting Burnt Offerings today. I'm not on the computer I saved all my info at, but I'll list some noteworthy details.
- I skipped Erylium, the Yeth Hounds, the Tentamort, and the Giant Hermit Crab. Erylium will appear, just not in combat. I'm planning to have her join the Scribbler when the time comes.
- I translated two of the events in Sandpoint into skill challenges: The Shopkeep's Daughter and Boar Hunt in the Tickwood.
- Gogmurt got some cool abilities: an aura that makes roots cling to the PCs' feet (in other words, difficult terrain), the ability to make a root attack and knock a single PC prone, and the ability to use burning hands as a recharge power.
- In contrast to Gogmurt, Warchief Ripnugget is just a Goblin Underboss.
- Lyrie is a Level 4 Elite Artillery, and Orik is a Level 3 Elite Soldier with the ability to shield Lyrie as an immediate interrupt; They are encountered together in the research room.
- Nualia is completely different in mechanics terms than originally written: as a follower of the goddess of madness, she has the divine power to wreak havoc on her opponents' minds. Several of her attacks deal psychic damage in a close burst, and different attacks inflict various status conditions. In addition, while Nualia's claw attacks aren't as likely to hit as her bastard sword attacks, they cause those who take damage to lose one healing surge. Basically, this Nualia was designed as an Anti-Leader who can shut down the abilities of Leaders.
- I used a solo barghest I found on another message board for Malfeshnekor. It possesses the ability to make shadowy copies of itself that serve as minions, but only exist for one round unless sustained as a minor action.
- I found that the XP I've assigned to each encounter would make the PCs level up once after clearing the Catacombs of Wrath, and a second time upon clearing all of Thistletop save Malfeshnekor.
