Fixed up all ranged combat, and added the final thing on my list in terms of equipment usage: ability-granting items. We decided to not use a spellbook/spell-learning system like most rogue-likes use, and instead went with a system where you have a list of abilities that you can activate, granted by the items you are currently wearing. This way, if you want to be a spell-slinging wizard, you end up wearing and using wizardly type items. If you want to be a big dumb barbarian type, you won't get spells, because the big dumb barbarian items don't give you spells (but you might get a Nordic Fury Axe Sweep or something ridiculous like that).
Anyway it is kind of hackishly placed in there. I've used different methods now for each of Monsters, Items, and Abilities, to see which one I liked best. So far the verdict is "none of them", but we'll see. Hopefully I'll decide on one way and then migrate everything into that pattern.
Gripping stuff!
