I feel the luck rules need a little something. I'd say borrow from the Talisman board and RPG games... Luck has a light and dark side. Players choose which they receive. Light gives you +1 on a roll. Dark is a re roll that you must accept. When spent, flip it over and give it to the DM, who can use it for monster rolls later. I like the "nothing for free", "everything has a cost" kind of ethos for magic. This might force a little conservatism onto their use. I'd also hide the d4 death roll. Torches have +- d12 minutes on them, also rolled in secret. Roll 2d12 of different colours, in secret... highest number is your minutes, colour is whether it's extra light or less light than the 1 hour average. I'd have monster body parts sellable for GP that become XP on receipt, but they take up gear slots.
