With this perk, Stealth Boys last twice as long while also granting sneak attack criticals an extra 10% damage. This perk makes a single Stealth Boy last 4 minutes (instead of 2).
- This perk actually affects all critical hits, instead of only Sneak Attack Criticals as description says.
- Only the critical part of damage is increased.
- When Logan's Loophole, Chemist, and Day Tripper are taken combined with this perk, Stealth Boys will last over twenty minutes. This translates to about ten hours of in-game time.
