You gain an additional vision of 3 meters(or hexes).
Maybe something like that?
Whoopsie, my fault. Forgot to add that "You gain" and "3" is a must one after another. So the only thing that can be done is to name the last component... So it could look like... "You gain 3 additional hexes of vision".
"How did they manage/How they managed"
Thanks! The second one is really bad, lol. Fixing now, will be up on next update.
