Pg. 241, 242 - The scribbler
- He has a +4 deflection bonus to AC, but nothing in his statblock grants it (no ring of protection or shield of faith spell). His AC should be 23 touch 14 flat-footed 19 .
Actually, it lists quickened Shield of Faith under his 4th-level spells (pg.241). That easily accounts for his +4 deflection bonus (due to his 12th level caster level) and would last for 12 minutes, or 120 rounds. And he has Protection from Good for +2 deflection, as back up if the Shield is dispelled or expires. And Greater Magical Vestment makes his breastplate +3 for the day, so there's the +9 armor.
The more immediate problem that I see, (and surprised that no else here mentioned it, so maybe I'm missing something) is that his attack and damage block don't take into consideration the spells he is capable of and which the adventure describes him as casting before combat. I'm assuming that per the stat block, he has bear's endurance and bull's strength on him, to account for his 18 Str and 19 Con, respectively. This means that without those spells, his Str is only 14 and his Con only 15.
His basic melee attack is Fanged Falchion +19/+14/+9 (2d4+9 dmg/15-20). Without any further spells cast, this is close to accurate: +11 BAB, +4 Str, +3 enhancement (extended Greater Magic Weapon), +1 weapon focus = +19 attack. But the damage is missing +2d6 damage for the Fanged Falchion's unholy property, which adds an additional +2d6 non-typed damage to attacks against good-aligned targets. I would argue that most PC's would be good, and even if not, this should have been noted in the stat block somewhere.
Also, being a Cleric, he has tons of buff spells and abilities that are not accounted for in the stat block, requiring the DM to do a lot of extra calculations. +2 more Str from Strength Surge can be discounted as it only lasts 1 round, overlaps with Bull's Strength and requires a round to cast (relatively useless power in combat), but he also has Righteous Might (+4 size bonus to Str & Con, grants reach) for 12 rounds, and quickened Divine Favor (+4 luck bonus to attack and weapon damage) for 1 minute. And when the 10 rounds of Divine Favor run out, he has Divine Power (+4 luck bonus to attack & weapon damage, +12 temp Hit Points and an extra attack at highest bonus) for 12 rounds. This would give him, based on the tactics listed, 22 Str and 23 Con for most of the combat, as well as reach and an extra attack.
So his melee attack would be fanged falchion +25/+25/+20/+15 (2d4+16 dmg. plus 2d6 vs. Good-aligned/15-20). And if he Power Attacks (and he probably will), it becomes +22/+22/+17/+12 (2d4+25 dmg. plus 2d6 against Good-aligned targets/15-20 crit). Ouch!!!
