So...
The human archer tries to attack Miles.
archer's roll 10 (+7 AGImod) = 17
Kabling's dodge roll: TBD

If he hits, it would be...
1 (+15) - 3 so 13 damage, leaving Miles with -1 HP.

The archer tries to go into stealth!
(disadvantage, thanks to the leg injury)
roll 1: 11
roll 2: 1 ...
The archer takes 2 damage from the failed attempt
5/15 HP remaining on the archer.

[@Kabling], mind rolling your dodge roll so I can post IC?
