Bloodseeker

Strygwyr the Bloodseeker is a melee agility hero imbued with dreadful powers to fuel violence and rip enemies apart in the heat of close combat.

He can drive targets into a maddened Bloodrage, increasing the damage of their attacks, preventing them from casting spells and bleeding their life in the frenzy. His speed is unmatched when he senses the blood of the dying, and from this perception none can escape. His own health is never a problem, as he can salve his wounds merely by bathing in the blood of the fallen. His ultimate, Rupture, sunders the skin of his victims, causing them to trail their life force behind if they dare to flee.

Tips

 * Bloodseeker, whilst being an efficient jungler and dual laner, is also a prime choice for solo mid, as it gives him easy access to the side lanes for ganking.
 * Reaching level six as quickly as possible should be a priority of the player; ganks should not usually be attempted before he has his ultimate.
 * Blood Bath gives Bloodseeker significant staying power in lane, healing him whenever he last hits or denies a creep.
 * An early Quelling Blade will help you get the most benefit out of Blood Bath.
 * Thirst is especially useful for allowing for clear targets on a team with no map vision or communication. Otherwise, its best for greatly increasing the risk under which weakened enemies move out or providing conditional speed.
 * Leveling Bloodrage causes it to turn into a steroid with a more powerful attack damage buff on every level, but it also serves as a powerful early game nuke and disable. The steroid effect on a fully-leveled Bloodrage is very powerful, often on par with the full arsenal of buffs carried by a given team.
 * Bloodrage should be cast on enemies beginning an engagement to prevent nukes. If Bloodseeker is laning against supports it is an extremely useful spell. Late game, it becomes a dedicated steroid for Bloodseeker or other carries or to twitch disable big caster threats such as Enigma or Earthshaker.
 * At level 3 it can be used almost continuously, since it has a short casting animation.
 * Rupture is one of the best skills to intercept an enemy hero that is chasing you or your allies, especially since it goes through magic immunity and does full damage regardless of armor and magic resistance. Heroes with high mobility like Anti-Mage, Lycan, Luna, Queen of Pain or Night Stalker suffer devastating damage when Ruptured as they are chasing or running away.
 * When ganking it is sometimes best to save your Rupture for when your target begins running away rather than right at the beginning of the gank. You may want to follow up on an allied disable using Bloodrage to silence the target and saving Rupture should the target not die during the initial damage done.
 * Each individual Meepo will add to the Thirst bonus stack.
 * Due to the passive Blood Bath being able to heal you upon killing any enemy unit. It is advisable not to spend gold on Morbid Mask, skipping therefore on Lifesteal items. Moreover, Bloodseeker should have a high damage output in order for faster killing, which subsequently gives faster healing.
 * Skull Basher or Abyssal Blade can opt to be taken if your team lacks disables and your enemies are using Teleportation spells like Town Portal Scrolls to escape your onslaught.
 * Force Staff, in conjunction with Rupture can cause significant burst damage (120/240/360) to enemy heroes by forcing them to move. It also serves as a quick escape tool, something that Bloodseeker does not naturally possess. However, it should be noted that the burst damage is relatively little to the level of your enemies and the level of your ultimate, and may just potentially push your target to safety.
 * Helm of the Dominator can introduce interesting new utility if Bloodrage is used as a steroid.
 * Armlet of Mordiggian can be picked up if you are confident in your killing power. It synergizes well with Blood Bath and Bloodrage's damage increase, but can also make you easier to kill, especially when focused.
 * Rod of Atos can give Bloodseeker even better chasing ability and can be bought if you don't want to rely on Sange's random Maim chance. However, the 25 bonus Intelligence is wasted on Bloodseeker.
 * Shadow Blade can be used to surprise your enemies, especially when they are alone. Backstab damage, movement speed and attack speed boosts your hunting ability along with your Thirst.
 * Bloodseeker is really good counter for Slark due to Thirst. You will make him unable to regenerate health from Shadow Dance when his hp is below 50%.
