Blood Tendrils is a threshold Attack ability, requiring level 75 Attack to use. When activated, it summons tendrils of blood to inflict a damage-over-time (DoT) effect on both you and your opponent, the damage in your favour. Blood Tendrils can kill players who use it at low health.
The DoT damage is proportional to the initial hit, which is 36-180% ability damage. The opponent will take 1/2 of the original damage with each hit, and the user takes 5/36. Both DoTs hit for four times, giving a total of 108-540% ability damage to the target and 25-100% ability damage to the user.
Freedom will clear the bleed if it was caused by another player, but it cannot clear the self-inflicted effect of this ability. The self-damage will continue even if the target is killed.
Because Blood Tendrils damages the user, it is advised to use it with caution. This ability deals relatively little damage to the player compared to Smoke and Shadow Tendrils, the magic and range counterparts. It is best used with Soul Split or a scrimshaw of vampyrism against weaker monsters with many life points.
Like most other damage-over-time abilities, the damage of this ability is not increased by:
- damage-boosting prayers/curses,
- additional damage applied by having boosted levels (i.e. from potions - note that this is a separate damage increase to the raw increase from having a higher level),
- damage increasing abilities like Berserk
- all variants of Void Knight equipment,
- the black mask and all slayer helm variants.
An alternative to Blood Tendrils is Slaughter, which is also a DoT ability. Blood Tendrils deals 108-540% damage and Slaughter does 250-625%, provided the target moves after its first hit. One should note that their target must move for Slaughter to deal maximum damage.
Blood Tendrils, along with Smoke Tendrils, Shadow Tendrils, and Ice Asylum, is learned by reading the Codex Ultimatus, which is obtained by talking to the Archaeological expert after The Dig Site quest.
Like with all damage over time abilities, the player is free to use other abilities while Blood Tendrils does damage to the enemy. The same does not hold for channelled abilities like Assault. This essentially means in terms of long term damage per second and assuming the enemy stays alive during the duration of Blood Tendrils, Blood Tendrils is just as good as an ability which does 108-540% damage in one hit.
