I still think the dragon eats both dudes, easily, which kind of puts them into their tiers.
Quick question, why is the dragon's Frightful Presence ability never mentioned?
A bunch of "Weak" minions (low level NPCs/Commoners and even PCs) will fail their DC21 Will saves *often* (if the dragon has not boosted it) and even though the Adept has a very respectable +14 Will Save (Adept Failure only 30% of the time) the rest of his "entourage" does not fare so well. Imp Familiar with +7 Will, Failure 70% of the time + Assorted warbeasts - I imagine they have TERRIBLE Will saves? (Note if Adept is Flat-Footed none of his Save/Maneuver items can be used) Undead zoo is obviously not affected which is a bonus for the Adept. Maybe I missed some buffs or fear immunities or something; if so I appologize in advance.
The monk with +11 Will (Monk Failure 45% of the time - quite worse than the Adept) The monk definitely has it a lot harder here, and as I've said multiple times, both guys are probably going to lose anyways.
-2 To "everything" (Shaken) is a pretty good debuff for "free", and consider that it also gives -2 to Initiative (Dex checks). If the minions happen to be particularly low level, then they are going to flat out Panic and flee.
The only things the monk has going for him is his slightly better stealth and that his initiative appears to be even (+9) with a Nerveskitter Dragon with Improved Initiative (also +9); if the Monk gets to roll initiative before failing his Will save at least his Initiative doesn't suffer, he also might get that one extra round of attacks in before the -2 kicks in. The zombie/warbeast zoo can be heard far away and the Adept/Familiar/Zombies have initiative modifiers in the 2-3 range? Sure the dragon has blindsense and the monk does not have darkstalker so at 60ft they roll initiative and see who goes first because the monk has a decent Spot; the Adept still looks like he is "automatically" getting Surprised, then Fear checks, then almost definitely losing initiative to a buffed, prepared dragon.
I also believe that the Monk has better flat-footed defenses than the Adept.
And for like the millionth time, I still think both guys are dragon chow with very little chance against a similarly optimized dragon. Oh, I should have noted Giacomo's Monk and JaronK's Adept; I think the stealthy Adept with the fingerdarts is probably better overall.
