Technically, this isn't an errata list yet; I'm going to point out all the errors in the NPCs listed in the Wormfood article in Dragon #355, some of which need some answers from the designers, Mr. Mona, or the characters' players. See, one of my PCs just made 6th level and took the Leadership feat, and chose DaeJin for his cohort. I started to transfer the stat-block into a character sheet, and noticed a LOT of things that didn't add up. So, I looked over all three characters and found a lot of errors. Here goes.
GAR BLITZHAME, dwarf Ftr2/Wiz2
• His AC is 17, but +1 scale armor only gives +5 to AC. He has no Dexterity bonus, and no shield, so where's the extra +2 coming from?
• He has 23 hit points -- 10 from his first fighter level, and 8 from his Constitution bonus. So he only rolled a [u]FIVE[/u] on 1d10+2d4? Either the math is wrong, or Erik is a serious dice-lawyer.
• It appears that he's lacking four skill points as a fighter. No matter how I divided up his ranks, he came up short.
DAEJIN MOON, half-elf Rgr4
• Due to her Intelligence bonus, she should know a third language.
• Her AC is 16; with studded leather and an 18 Dexterity, it should be a 17.
• She has 26 hit points: 8 for 1st level, +8 for her Constitution bonus, so she rolled a 10 on 3d8 -- somewhat below average. Again, this might just be Erik being strict on dice.
• Her Reflex save should be +8, not +7.
• Her Will save should note the +2 she gets against Enchantment effects.
• She has a +4 base attack bonus, and a 16 Strength, but only a +5 to hit with a longsword, and only 1d8+1 damage? It should be +8 to hit, and 1d8+3 damage (1d8+4 if two-handed). Likewise, her attack bonus with a +1 composite shortbow is only +6, when it should be +9. Her shortbow damage is listed as 1d6+2, when it should be 1d6+3.
• The bonus feat from her combat style (gained at 2nd level) isn't listed. I'm assuming she took the archery style, so she gets Rapid Shot for free.
• What is her favored enemy? Just as a guess, I selected magical beasts.
• What's her wolf's name?
• She should have 49 skill points ((6+1)×7), but has spent only 32.
• Her gear list didn't list her longsword.
TASSILO VINIESE, human Clr4
• Due to his Intelligence bonus, he should know a third language.
• His AC is 14, but with a chain shirt and an amulet of natural armor +1, it should be 15.
• He has 22 hit points: 8 for 1st level, +4 from his Constitution bonus, so he rolled 10 on 3d8. Pretty low. See above.
• His Will save should be +8, not +7.
• His ranged attack bonus with a masterwork light hammer should be +4, not +3.
• Because he has more than 4 ranks in Knowledge (religion), his turning check should be +3.
• He should have 35 skill points ((2+2+1)×7), but has spent only 33.
• His longsword isn't on his gear list. And why did he get a masterwork hammer, when he obviously favors his longsword?
