In my previous Comet revision, I've managed to collect put 402 + 542 MATK in exact (I think it was before +9 FAW?, suck I lose the build screenshot already).
That alone, total MATK is: 1160.8 +MATK (includes sMATK, eMATK, wMATK). Misc. MATK...damn I forgot already lol, but there was some buffs/items that can increase it (one of it is Box of Drowsiness - this one didn't added on MATK window, hence Misc MATK)
My demi set showed me I have +86 %MATK towards demihuman (1.86 %MATK) I believe the 2.01% mod can be achieve, however.
Without FBH, that can deal around 20k - 25k to WOE set with that set. I've tested it with a friend's sura but only in GvG room, which he also stacked demi reduc too (normal situation in WOE). In WOE, I don't have cross guild friends to take the ss of it LOL (=.=)
IIRC, my %MATK mod is 1.23 %MATK, from 3 gears.
It is therefore, the final calculation is:
Total MATK: 1160.8
Overall MATK: 1160.8 * 1.86 * 1.23 = 2655.678 MATK
MA'd: 2655.678 * 1.5 = 3983.517
Quite low, isn't it? Well, I think that's the average of most WL in the server, with easily accessed foods, buffs, and gears. Again, numbers is numbers. What matters more after that: SKILLS!
The way of cometting, as from my experience, should be in a chained, short and captures huge range. But if can, try learning to quad comet under 5sec. I've recently obtained the reflexes to do it, and it was...SUPAH AWESOME! /gg
