Bleeding (5e Disease)
From D&D Wiki
When a weapon causes Piercing or Slashing damage, removes a limb, or otherwise exposes flesh, the affected player must roll a Constitution saving throw. On a failure, bleeding comes into effect. The DC of this saving throw is unique to each severity level, as listed below. If the attack deals damage equal to half of the player’s maximum hit die roll or less, they have advantage on the saving throw.
The effects of Bleeding are as follows;
There are five stages to bleeding and 4 levels of severity.
Level One Severity: If a creature scores an attack roll that is 1-2 higher than your AC, then the wound is minor, you have 3 rounds before the Bleeding stages come into effect. DC 10.
Level Two Severity: If a creature scores an attack roll that is 3-5 higher than your AC then the wound is alarming, you have 2 rounds before the bleeding stages come into effect. DC 13.
Level Three Severity: If a creature scores an attack roll that is 6-8 higher then your AC then the wound is serious, you have 1 round until the bleeding stages come into effect. DC 15.
Level Four Severity: If a creature scores a critical on their attack roll, then the wound is crippling, The first stage of bleeding comes into effect instantly. DC 18.
Stage of Bleeding
Every other round (12 seconds) that a creature is bleeding, they must succeed a DC 14+Stage Constitution saving throw or
Stage One: Blood starts coming out of the wound, causing you blood loss and dizziness. Your movement speed is reduced by 5.
Stage Two: Blood continues pouring out of the wound, causing you a high amount of pain. You cannot cast spells that require concentration.
Stage Three: Blood loss blurs your vision, clouding your sight. You have disadvantage on Passive Wisdom (Perception) checks relying on sight.
Stage Four: Enough blood is lost to make you fall unconscious.
Stage Five: The amount of blood loss causes you to die.
Bleeding can be cured with lesser restoration . If Bleeding is at stage 3 or higher, you will need greater restoration. If the weapon has a magical bonus to it, you need to cast a spell slot higher to heal it (eg. +3 longsword needs a lesser restoration of spell slot 5 or higher). Any effect that would stabilize a creature can be used to reduce Bleeding by 1 level.
