Blowdarts could be very accurate and do almost no dmg, mostly to stun and stagger.
Lets not get too fancy, where is my shit-on-a-stick-poison-arrow?
Swing you weapon once in shit that is on the battlefield, and you get a +2 dmg on your next swing or reduced agi stats for a short while
Caltrops are great, really want them ingame, so many possibilities.
Not soo keen on grenades. But maybe argue that the firebomb be reintroduced, it was great.
Also, for siege. Large Rocks, only throwable maybe a meter out. For massive blunt dmg on people climbing ladders.
