This build is a dagger and claw (Wierd I know) wielding slayer which uses viper strike to produce big DPS while instant leeching and overleeching to stay permanently healthy.

This build gains most of its offensive and defensive powers from two unique items: The bloodseeker Hellion's Paw and Bino's Kitchen Knife Slaughter Knife. The former item makes all hits with the item instant leech and the latter allows us to overleech as a Slayer and proliferate our poisons for clear. Since viper strike hits with both weapons at the same time we get both benefits at once. This allows our character to heal absolutely insane amounts of hp per second instant leeching around 7000 hp per second and overleeching 3000 hp per second for 10 seconds even on one target. To achieve this leech we focus on getting lots of leech nodes on the tree and using proper support gems as poison skills have very low base damage.

Since these two uniques are low pdps weapons we use viper strike which has some of the highest innate melee gem scaling in the game to reach respectable damage numbers (13 mil DOT dmg or so) Something to keep in mind is that viper strike's damage is a ramping ability so it can take close to 10 seconds to ramp to this level of damage!

For clear we buff our extrastrike distance by 30% from the tree. In addition we grab two extra strikes from gloves (or +1 strike annointed on an amy/ancestral call in the early game) so we can turn this strike skill into a respectable semi-ranged option against bosses and packs. Binos poison prolif will fill in the gaps between your striked targets melting them down.

For flasks we mainly focus on defence and sustainability by getting "Gain # charges when you are hit by an enemy" prefixes and defensive suffixes, along with the instilling orb's "use when flask is full" on all our utility flasks.

This build uses life gain on hit as well 2% max life recovered when killing an enemy. The hidden secret is also a flagellant's eternal life flask which will get a use every time you are hit twice by enemies. Due to passives on the tree this flask will heal approximately 5400 health over 1.7 seconds. During no leech maps you would simply spam this flask throughout the map. (You can do this all the time if you want to but I dont know if it is necessary) You can also swap out this flask entirely if you wanted to just roll over no leech maps!
