I use luck for skill gain. When you hit a monster, it calls back to a skill/stat function that randomly gives a gain between nothing, and 0.2, similarly with loot you have a chance at 0 items or a few, as you kill harder monsters it increments the bottom end of the roll so you get between 1-3 items from a hard monster instead of 0-2 for an easier monster.
Killing a monster and opening a grave is like opening a present as you might get a high roll or low roll of items.

Addictive Gameplay: What Casual Game Designers Can
With my experience playing pokemon(yes, it's not as bad as it sounds) as a child, and later Final Fantasy, I can say luck is generally hated by the community in PvP situations and also for random encounters. For me, I say that it's more acceptable if the randomizing damage makes littles difference and is just to make it less predictable, but having luck be a large factor is a sure fire way to make a large crowd mad. Just my two cents though.
I'm making a video game with my friends but we need a graphics coder and possibly a C++ coder. If you are interested, please contact me by sending a message.
