Potions still don't anything.
Neither do scrolls.
Although it probably doesn't matter because
a) potions are terrible and
b) paying 5000 of my hard-earned (read: exploited) gold for a measly 20 seconds of haste boost is awful.

0 AFDL: 636
1 AFDL: 731 (1.1494)
2 AFDL: 1462 (2.2987)
3 AFDL: 2194 (3.4497)
4 AFDL: 2925 (4.5991)
Substituting my Doomblade of Destruction with a different +15% damage weapon, such as Burning Blade, has also resulted in the same numbers.
Racial boosts like BLOD also seem to be functional now, rejoice.
Here are the same numbers I just did but with BLOD instead of Doomblade.
The first number is comparing to normal, the second is relative to the BLOD number.
BLOD: 960 (1.5094 - 1)
BLOD + 1 AFDL: 1104 (1.7358 - 1.15)
BLOD + 2 AFDL: 2208 (3.4717 - 2.3)
BLOD + 3 AFDL: 3313 (5.2091 - 3.451)
I don't have Doom Lord Sepulchure Helm (+25%), but given how the numbers seemed to be predictable for the rest of these, it seems like it's fine.
From these numbers we can see that each AFDL item is giving 1.15x damage (rounded), which is getting stacked together but not compounded ;-; and so having 4 AFDL gives 1.15 + 1.15 + 1.15 + 1.15 = 4.6x damage.
Also, 4 AFDL + Yakitori Pet still gives like 7.15x rep boost. I've been using that combo to get a lot of rep from that Loremaster DN daily. Probably won't do anything but it's better than getting just a piddly 150 from it.
Using a rep boost on the normal server and then switching to Test gives you another +1x which brings it up to 8.15x total. I don't really want to check turning in with fewer than all my equips decked out. Just know that the amounts self-stack even more than the AFDL damage boost.
