{2.0} Budget Tempest Dagger Reave

Bandits:
Oak +40 Life
Kraityn +8% attack speed
Alira +1 max power charge

Although I used a Shadow, Ranger is more optimal by a couple of points.

Level 94(last few levels I'm just picking up frenzy charges):

If you are ranger (Level 92, more optimal):

Offense:


Reave - Melee Physical Damage - Multistrike - Fortify - Increased AoE - (Increased Crit Damage/Added Fire)
My planned 6 link is either increased crit damage or added fire. Use PCoC instead of Increased AoE if you don't have a Death's Hand for power charge generation. When you get a Death's Hand, Increased AoE will help your clear speed more than another damage support. If you want to go full dps mode, use Added Fire instead of Fortify (SC only). Physical reflect maps are not worth attempting in my experience, even if you have a Phys to Lightning and Life Leech instead of Increased AoE and Melee Phys. With enough leech, vaal pact is an option for the ability to run phys reflect, but then Blood Rage becomes annoying to use. Single reflect mobs are a complete non-issue, and now that Thornflesh is removed, we have no worries at all about reflect in normal maps. DPS with the 5 link is sitting at ~33k at the moment, not taking into account the dual wield bug, so it is quite a bit higher in reality.


Vaal Reave - Faster Attacks
Multistrike does not help us, as VReave already adds seven extra attacks.

Note: No golem, not because of the slots, but because I don't like having to worry about it. I'm scared I will forget de-spawning it in a chain map.

Buffs:


Hatred + Arctic Armor.
The chill/freeze/shatter from Hatred is great for both offense and defense. For elemental weakness if you aren't overcapped, run Purity of Elements + Herald of Ash + Arctic Armor instead. If you feel like running more dps, you can substitute a Herald in for Arctic Armor, but personally I've run AA the entire time it has been available.


Increased Duration - Blood Rage - Vaal Grace
It is important to have this setup in one of your weapons, being able to toggle off your Blood Rage is a convenience factor, especially in Vulnerability maps. Run Vaal Haste if you want to for the deeps, although I'm quite happy with Vaal Grace.

Defense:


Whirling Blades - Faster Attacks - Blood Magic
Makes movement speed on boots irrelevant for the most part, and with the attack speed on the tree, makes traveling incredibly fast. The 30 movespeed on my boots is nice for stuff like Haku missions but that is about it. Blood Magic is necessary, as we don't have enough mana regeneration.


CWDT - Increased Duration - Immortal Call - Enfeeble
Pretty self-explanatory, physical immunity and auto-enfeeble. This works really well in conjunction with Daresso's Defiance, if you get hit with enough damage to proc the CWDT, you all three endurance charges consumed toward your Immortal Call. The level you have the CWDT gem at is personal preference, I have mine at level 4. Remember to not level IC above the level requirement of your CWDT gem.


CWDT - Arctic Breath - GMP - Chain
Chilled ground, chilled ground everywhere. Even though we are running arctic armor, this just spreads the chill even more. It is essentially a free temp chains. Get the lowest CWDT you can, we want this proccing as much as possible.

Gems in offhand for swap depending on map mods:

Weapon:

Try aiming to get a dagger with 250+ physical DPS and local critical strike chance above 8%. The dagger I am using has 270 pDps, but a gg dagger will easily exceed 300 pDps.

Offhand:

Death's Hand is BiS at the moment in my opinion. It gives you power charges as well as Unholy Might (30% of physical damage added as chaos damage). This is something you should go for after getting a good dagger, as there are other great options to run before you get one.

Lavianga's Wisdom gives you increased AoE and damage (and a small amount of life), and we don't care about the movement speed penalty because of whirling blades.

Relentless Fury offers culling strike and onslaught, as well as chill immunity while under the effect of onslaught.

Going shield is an option if you are feeling defensive. If you go this route, spec out of the dual wield nodes around Duelist, and make sure to get a high evasion shield. I would recommend the shield effect node Precise Interception, it will give you a huge evasion boost.

Soul Taker is the other late game option, as you no longer have to worry about mana and you get to run another Herald. Mana is generally not an issue though with enough physical damage and the leech you should have. You might consider picking one up at some point to swap for 80+ maps with enfeeble + monster phys reduction + endurance charges, although I don't think it is worth the investment until you are really maxed out on your other gear.

Helm:

As for all our gear, make sure to get high life. The things you really want, but don't absolutely need: good accuracy, high evasion, and resists to cap you off. If resists are not an issue, I would recommend a Starkonja's for a cheap mix of both good defense and offense.

Standard variants of this build can use a Rat's Nest; I don't think it would be worth to lose the life for Tempest.


Amulet:

Try to get crit multi on your amulet as well as life and some strength/int. Accuracy, crit chance, or resists are a bonus.

Rings:

Accuracy is a big deal for crit. The more you get the better off the feel of the build will be. Other than that, resists are a big thing you should be going for on your rings, along with life (ok I'll stop mentioning that).

Belt:

A rustic sash is nice for offense, but a Leather is great for life and Heavy belts offer some extra life and much needed strength. Get resists, and weapon elemental damage helps a little. Flask effect duration is often overlooked, it is a big bonus.

Chest:

Daresso's Defiance doesn't offer the most in terms of raw evasion, but has the benefits of endurance charge generation on kill to power your IC duration, some extra dodge, leech, and occasional onslaught. For the price it is pretty hard to beat. Other than that, a high evasion rare would be very good, and for early mapping, a cheap 5 link is an option as well.

Gloves:

I didn't mention it earlier, but if you can get mana leech on any of your jewelry slots, that will power your mana sustain. If not, get gloves that have some or have the open slot to master craft (can't craft mana leech on jewelry). Gloves are yet another piece we can get accuracy on.

Boots:

Movement speed is not a necessity, as we have whirling blades, which allows you to get a huge amount of resists with this slot.

Flasks:

Get a couple pots with bleed removal, one with freeze immunity for boxes, and one for curse immunity. Having one with shock immunity is nice, especially maps with shocked ground. Surgeon's prefix on flasks is really nice for more uptime.

Shield I was using:
Bought this very early in the league, could definitely do a lot better with evasion and life.

I'm pretty bad at providing leveling trees, as I just spec into what I feel is necessary at the time when I play. Traveling to duelist to begin with is a good idea, you get life regen to run blood rage and some decent damage. Also, hold off on going into crit early or any dagger specific nodes, as this allows you to use any good weapon you find leveling, or something like a Lakishu's Blade for example. I don't know where these trees will put you on your life pool, but to be safe, I recommend 1200 life for Malachai on normal, and 2400 for cruel. The trees below use some nodes that we will spec out of late game, but the given passive respecs are more than enough, you won't need regrets.

Again, these are just kind of outlines, I would use the end game tree as something to work towards instead but this has been requested a lot.

I only recorded one map so far, a 76 gorge. Lots of devourers unfortunately :C. Tried to showcase the difference between reave and vaal reave this map, and how strong the mobility can be.
