Question about Str/Luk shadowers

So I have a few questions:

1)Are Str shadower daggers affected by Luk as well?
2)How should I raise my stats and what kinds of equips do I use for str shads? Because all regular theif equips have a Luk requirement.

STR Daggers are only affected by STR and DEX, not LUK. In addition, STR Daggers have a higher base of 2 from the LUK Daggers. In example, GDK's Average is 95, Blood Dagger's is 93. The maximum amount of STR you need is 75 to wield all STR Daggers and shields. DEX will differ.

If you can, try to keep your STR low (and in addition, DEX). The most I would raise it to is 50 Base STR, while having equipment for the rest. And in the process (unless you have quite a bit of STR gear), lower the base. Ignore the STR on your Shield that is added by scrolls, unless you want to use MW20/30 everytime you want to reequip.

Also, if you have a lower base STR/DEX, and a higher base LUK, Maple Warrior will affect you more, due to it only affecting base.
