3. Deadshot · Each Crit Hit by non-melee weapons grants +5% Crit DMG, up to 45%. The effect is removed upon the next reload. Crit rampSource

   Stacking Crit DMG per crit, reset on reload; high uptime on the high-fire-rate MG4.

   Big weakspot burst on the first hits after each reload; synergizes with the constant-reload Fast Gunner loop.
