Landing a killing blow in V.A.T.S. will immediately restore all Action Points, allowing the beginning of a new series of attacks immediately. However, foes killed by allies (or other means) will not trigger the perk, even while in V.A.T.S.
Fallout: New VegasEdit
In Fallout: New Vegas, the perk only gives back 20 AP on a kill in V.A.T.S. Although this is a significant reduction to the effectiveness of the perk, the perk is still very useful with high power, low AP cost weapons. The effectiveness of Grim Reaper's Sprint is dependent upon three things: AP cost of the weapon, damage of the weapon, and toughness of the enemy.
Be aware that the perk restores 20 Action Points if an enemy is killed in V.A.T.S., not per enemy killed; e.g. killing 3 weakened enemies in a single round of V.A.T.S. will only restore 20 AP, not 60.

When fully maxed out, this perk can be incredibly useful in the mid to late game, particularly in large battles. This is because higher level enemies are often accompanied by lower level "cannon fodder" types, who can be instantly killed at higher levels. These enemies essentially provide a reasonably reliable source of regaining Action Points, since at higher levels they can usually be killed in one or two shots, with a 35% (at max level) chance of activating Grim Reaper's Sprint.
- If a companion, the Mysterious Stranger, a car explosion, or the explosion caused by targeting an enemy's grenade kills the target, AP will not be restored. This also happens if the enemy dies from splash damage, the Tesla cannon's electrical field, or lasting effects like burning or electric shock (i.e. flamer, Jingwei's shocksword).
- Knocking an essential non-player character unconscious counts as "killing" them for the purposes of this perk.
- In Fallout 3, the G.E.C.K. script actually gives 1000 AP after a kill, rather than restoring the exact amount of AP.
- Be aware that in Fallout: New Vegas, some weapons will not gain another shot in V.A.T.S. from only 20 AP. Even in this case, the perk retains some usefulness in that it does allow going back into V.A.T.S. sooner and fire again, even if one cannot immediately return to V.A.T.S. and fire again.

- ps3 Getting the perk can very rarely (confirmed on two different accounts) give you a lot of negative karma, making you evil. [verification overdue]
- pc APs gained through gear in Fallout 4 will not restore. (a total of 195 APs, 30 APs through ultralight mod, Grim Reaper fills APs up to 165.) [verification needed]
