Adv. Dark Aura

I've noticed some really "off" DoT damages from it since 1st SP into it. I'm really wondering how the formula for it goes..

Just did a few simple tests right now up at Lycanthropes & Werewolves and it seems...

1. MW seems to affect the DoT damage
2. Bless's MA seems affect the DoT damage
3. Body Boost Dark Aura's +% boost seems to affect it
4. Magic Defense buff on monster's affects DoT damage

The formula, min range x 130% Battle Mastery x (100% + Adv. Dark Aura DoT %), seems to fit the minimum DoT seen. However, the max DoT seen using this formula(using max range of course) is off quite a bit..

9142 ~ 12189 range with the following buffs
Max Bless (+15 MA)
Maple Warrior level 19: +10% all base stats
Max Battle Mastery: +30% damage, +20% Minimum Critical Damage
Max Body Boost: Dark Aura: +40% for 60 seconds.
Advanced Dark Aura level 25: +19% damage done, 90% DoT per sec on nearby enemies
--> DoT range: ~22-32k
