Buffing Elves? What heresy is this?
Just kidding.
Some thoughts on stuff.
> anyone wants to get in here and start making the mod t themselves
The weapons sound interesting. I might do them.
> Firstly, we need a harder, heavier wood.
Barring appearances, what makes trees different is their material. Making that harder, heavier wood is relatively easy. Using the example of glumprong, you can edit the density and hardness from the wood template to your liking.
> Elves can be buffed based on innate skills without going against the current fluff.
Yep, I may suggest improved skill rates for this, though, in addition to default skill levels.
> I think that Elves should be naturally strong climbers, which I believe will make them more likely to path into the fort via climbing.
I am not too sure about the effect of skill level on pathing, but you could also give elves a climbing gait with a much higher speed than other creatures, which would make them faster and stuff when climbing.
> Elves have good eyesight from their hunter-gatherer foraging lifestyle, so why not give them innate skill with ranged weapons?
An innate skill with ranged weapons can be waved away as a product of their society. But I'll suggest increasing their VIEWRANGE to replicate good eyesight.
> It also would help to give them an extremely diverse armory, so the player would be continuously challenged by changing 'elven tactics'.
It would also help to reduce the amount of melee weapons they have, because, currently in terms of melee weaponry, wood < metal.
> causing extreme pain and bleeding.
Edge attacks cause less pain than blunt ones because they do not break bones. So I'm not too sure about how you are going to do the extreme pain bit.
> Clubs
Game-wise, I do not see the difference between macanas and clubs. Both break bones while macanas can cut unarmoured things too.
> the weapon itself should be a viable stabbing weapon made of hardwood/flint/obsidian/jade
If I remember correctly, you can't control what material a weapon is made of short of limiting the civilisation's access of weapons grade materials.
> Slings
Sounds nice. Not really much to comment on except that elves will be shooting wooden sling ammunition.
> cause extreme pain in their targets
Breaking bones I presume
> low weight and hardness.
The thing is, to have an effective blunt attack, you need weight.
> Poisoned arrows
Masterwork had this sort of thing, but I'm not sure if it was the DFHack-ed bit or not.
> Other stuff
All are feasible and interesting.
