Tomb Raider (2013) · Bow reinforcement
Bolt reinforcement
Bolt reinforcement is a salvage funded bow upgrade whose listed effect is increased damage.
How it works
The bow upgrade table lists Bolt reinforcement as available for the temporary longbow, with 250 salvage and damage increase as its effect. The broader weapon passage says reinforcements are applied at camp using salvaged items. The table supplies a tier condition and numeric cost, but no damage amount.
