About the Sentinel
The sentinel is a Sniper Rifle that uses Sniper Ammo and does 65 Damage Per Second with a maximum of 65 Damage Per Shot. It takes 3.5s to reload an empty magazine and 2.5s if you have some ammo already in the gun.
What sets the Sentinel apart from any other weapon in the Apex Legends arsenal is its unique ability to consume (over 5 seconds) a Shield Battery from your inventory in order to enter a temporary charged state. During this charged state, each shot is a guaranteed 100 damage to the target enemy’s shields. Your time remaining in this charged mode is displayed as a bar just above your weapon in the bottom-right corner. This bar will gradually deplete over time, and it will also be reduced by chunks each time you fire.
The sentinel can attach 1x Holo, 1x HCOG "Classic", 2x HCOG "Bruiser", 1x-2x Variable Holo, 3x HCOG "Ranger", 2x-4x Variable AOG, 4x-8x Variable Sniper, 4x-10x Digital Sniper Threat, Extended Sniper Mag: (Common, Rare, Epic), Sniper Stock: (Common, Rare, Epic)
