L54 Damage Calculator
Every possible 2-weapon combination from the full weapon database is tested against every 2-item combo you can build from your set.
All calculations use expected average values from each weapon's icon ranges.
Soft lock — opponent combo ties or beats every one of your combos.
Hard lock — opponent combo strictly beats every one of your combos.
