Hiya.
GWF: "You have Disadvantage to hit [with -2 if you already are at Disadvantage], but any hit with your weapon will do at least average dice damage. For example, a weapon with 2d6 damage will do at least 3 points on each die; rolls under 3 count as 3 (i.e., a roll of 1 and 5 would do 8 points, not 6). A Critical Hit will do maximum damage for both rolls (i.e., 2d6 damage critical would do 24 damage)."
Sharpshooter: "Pick a single missile weapon (short bow, throwing dagger, sling, etc.). If you have at least one full round to aim and watch your opponent, you can not suffer Disadvantage on your attack due to range, cover, etc."
There's two off the top of my head.
