Rally or "Rally Potential" is a mechanic that allows players to heal without a personal buff or consumable.
Upon being hit or taking fall damage you can hit enemies to regain health. Interestingly, as the rally mechanic is based upon the in-game effect of "bathing in your enemies blood", enemies can still provide health for several seconds after death. How much health is determined by your weapons' innate Rally Potential. Most large weapons have good rally potential to compensate for slow swing speeds.

Best Rally Potential Weapons
The following are the three weapons with the best Rally Potential
Do note that one can rally more than once in one swing, should it attack multiple times or hit several targets, this is especially true when using a weapon that has a whip form such as the Threaded Cane, Beast Cutter or Amygdalan Arm.
Rally can be advantageous if fighting multiple enemies or when using a weapon with rather high rally potential, wether innate or boosted by Blood Gems.
- Weapons with great Rally Potential can be utilized to a great effect in PVP when using a Lead Elixir as this allows players to not be as easily staggered by enemy players, thus being able to trade blows while recovering health.
- Attacking enemies while they are in their "death animation" will result in rally. It is unknown if this is a bug or a feature.
- Rally is important to the world of Bloodborne as a concept itself as players are rewarded by attacking despite how dangerous of a situation they are in. It also ties in with the "blood-drunkness" of certain individuals.
