1: permanent effects are absolutely planned, incorporated in an overarching injury and dismemberment system :) It might as well stretch to include psychological traumas as well.
2: 100% planned with our event system. Thats going to be so much fun :)
3: Im not a big fan of consumables, as its a little micro-managy and people tend to hoard them for the great emergency which finally never happens and they sit on their stuff. So maybe, but probably not.
4: Already on our backlog list.
Cheers!
