Let's Temporarily

+_+

If you equip the gear in this order...
4 luk base
19 luk - Zak Helm [15 int]
41 luk - Horntail Pendant [22 int]
42 luk - Starlight [4 int]
43 luk - Black Salt Shoes [1 int]
43 luk - Dark Arten [3 int] -> or Flamekeeper Cordons if you're a rich pineapple

Total equipped from gear is 8 int.
39 luk base
54 luk - Zakum Helm [15 int]
76 luk - Horntail [22 int]
78 luk - Requiem [5 int]
79 luk - Dark Lorin [4 int] -> again, Flamekeeper Cordons
80 luk - Gold Lapiz Sandals [3 int 1 matk]
80 luk - Doomsday Staff

The lukless has 8 int from gear, low luk has 13 int. Flamekeepers decrease that gap by one. (13 vs. 17)

So for 35 luk (and int lost), you gained 42-43 int/matk on the Doomsday Staff over a Shine Wand. I guess that's worth it if you can get similarly scrolled lv.70 mage gear to lv.35-40.

for the lukless, aren't the yellow snow shoes better?
