Blood curse of the slow trick

This blood curse allows the user to control what the enemy sees after 1 turn but only if they are weakened first. This curse makes all enemys have disadvantage on rolls (like to hit a player or to dodge). If the enemy misses a hit they take 1d10 of their health. 

This blood curse means three of users unconscious party members will get up untill the Blood Hunter who casted the blood curse is downed

At level 5 this spell will allow the user to rise an additional 4th party member and will make enemies take 2d10
