The current battle system mainly calculate everything from Your Rank vs Mob Rank

[Peregrine]

All magic does that...aero on brags does teh same thing. At basic INT and PIE, you get big resists and hit for 80. At 90 INT and PIE you start hitting for 200-300. At 174 INT and PIE...well it's pointless. You hit a wall at about 120 at most and the only way to get better, past half-assing your job because doing more than half-assing it is pointless...is to level up. Then holy crap suddenly your nukes hit for 600 instead of 200.

I dare any R50 conjurer to NOT spirit dart Uraeus for 33-35 damage. Dare you. Can you even do it? I know you can't do better, but can you do WORSE? I don't even know.

How MUCH can I strip and still do that? Well I can strip to a NQ jade crook. I can stop eating food. I can despec 50 INT and PIE points.
I can accidentally wear my crafting gear. Kid you not.

What do I have to do as a R50 conjurer to not hit Uraeus for 33-35 damage? Seriously. Guess what my criticals do to it. Holy crap 33-35 damage. Amazing. It's like NOTHING EVEN MATTERS BUT LEVEL

Once again taking out dlevel would probably just leave you stuck at 33 damage forever, its most likely its not the dlevel effecting your lack of anything mattering, but rather the base defenses of the mob you are dealing with.

Since your stats arent breaking through his, your dlevel is the only factor. Im used to this, this is what it was like trying to do damage to tiamat on monk. nothing had any effect, except chi blast, and they reduced thats effectiveness by like 1/2 so people couldnt just use skills that ignore defense.
eating meat, adding attack, unless i boosted like 5+ times i would barely see an effect. Of course when i boosted like 12 times, wow its like a slightly strong normal monster. too bad 12 boosts meant i had 999 attack and there was no way to get that normally.

The NMs are not a test of dlevel, because NMs always have ridiculous stats. to test dlevel effects test your damage versus mobs of the same name, but different levels with the same equipment, i have so i know dlevel doesnt explain the phenomena you are talking about
