More testing with Demon. This ability:
Demonic Aspect
Demon adopts the aspect of Kalavakus, gaining a bonus on all Perception, Athletics, and Use Magic Device skill checks equal to half of the Demon's mythic rank plus one. Those bonuses do not stack with other bonuses from demonic aspects.
While in demonic rage, the Demon with an aspect of Kalavakus gains a +2 bonus to CMD, CMB, and natural armor to AC. The bonus increases by +1 at 6th and 9th mythic rank.
Whenever the Demon with an aspect of Kalavakus succeeds at a combat manuever check during a demonic rage, the Demon can make an attack against that target as a free action. When the Demon with an aspect of Kalavakus hits with a charge attack during a demonic rage, the Demon can attempt to disarm the target as a free action.
is completely fucked. In my testing I am getting 10 free attacks whenever I charge something. I have no idea if the number of attacks is tied to anything - I tried increasing my available AOOs and it didn't change the number. Anyway, supposedly the aspect triggers a disarm action on the target, which provokes a 'free attack'.
Only there is never a disarm action taken in the combat log. Oh sure, a disarm actually takes place (i checked, the target was actually disarmed), but is there even a saving throw? Who fucking knows. What determines how many bonus attacks you get? Who fucking knows.
It gets juicier:
Demonic Aspect
Demon adopts the aspect of Schir, gaining a bonus on all Lore (Nature), Mobility, and Athletics skill checks equal to half of the Demon's mythic rank plus one. Those bonuses do not stack with other bonuses from demonic aspects.
While in demonic rage, the Demon with an aspect of Schir gains a +2 bonus on melee attack rolls. The bonus increases by +1 at 6th and 9th mythic rank.
During a demonic rage, the Demon with an aspect of Schir gains a Powerful Charge ability, increasing the number of weapon damage dice by two and applying an additional one and a half of the Demon's Strength bonus to damage from the charge.
This thing isn't increasing my weapon dice by two, it's increasing Grave Singer's 1D12 to 5D12. Which then gets multiplied by your effective crit modifier (which currently I am aiming to push up to x5). So the base weapon damage can end up at 25D12. (note that it doesn't stack with other increases to your weapon die, such as Size or Lead Blades - though those will count for subsequent attacks)
The STR mod to damage is just as nutty - my character currently will have a STR modifier of +27, +40 on 2H attacks, so Schir increases the STR mod to damage of this charge attack (but not the subsequent free attacks, note) to
+80.
