Nested Sniper

Requires proficiency in crossbows or firearms.

• Being prone does not impose disadvantage on attacks you make with a crossbow or firearm with which you are proficient.
• While prone with such a weapon, long range also does not impose disadvantage.
• You can spend one action or one attack to grant yourself advantage on the first ranged attack you make before the end of your next turn. If you are prone when you do this, you instead grant yourself advantage on all attacks you make before the end of your next turn. Moving, standing back up or being within 5 feet of a hostile creature cancels this effect.
