Blood Frenzy

You touch a willing creature, launching them into an empowered frenzy. For the duration, all attacks against the target creature have advantage, but the target gains the following benefits:

• The target is immune to the charmed and frightened conditions.
• The target has advantage on melee weapon attack rolls.
• When taking damage would reduce the creature to 0 hit points, they must make a Constitution saving throw with the DC equal to half of the damage taken. On success, they are reduced to 1 hit point instead.

If you are the target of this spell, you automatically pass saving throws to maintain concentration on it as a result of taking damage.
