Lethal Weapon

The Lethal Weapon O/S Upgrade increases damage of melee weapons by 35%.

Strategies

 * Essential for melee-focused characters. Don't take this upgrade if you plan to do most of your fighting with ranged weapons.
 * Provides roughly the same damage upgrade as Smasher for most melee weapons (excluding Crystal Shard, where Smasher is way better), but allows for faster attack. Thus, planning to get both, Lethal Weapon should be acquired first.
