PoE 3.12 Flashback Starter Builds | Fast, Cheap, Endgame

Flashback is the last league event of Path of Exile in 2020. Players will randomly encounter monsters and themes from previous league on the map. In the Flashbach event, the higher the level, the better the chance of getting official prizes. Poe4orbs recommends some popular starter builds to you, if you haven't joined flashback, you might as well take a look

[3.12] PoE Flashback Necromancer Raise Spectre Witch Starter Build - Endgame, Easy, Fast

This build is designed as a league starter and SSF build.

This summoner build uses spectres as the main damage dealers. Spectres are 'ghosts' of monsters that you kill. You can find hard hitting melee spectres, fast map clearing spectres and everything in between. This gives a spectre summoner a lot of flexibility depending on what you want to focus on

It will take you from a fresh league start all the way to endgame bossing on cheap or self-crafted gear.

It is focused on tankiness while still having good DPS.

[3.12] PoE Flashback Shadow Trickster Toxic Rain Starter Build - Fast Mapping, Cheap

Build Mechanics

Toxic Rain: Toxic Rain shoots out a base 5 arrows (pods). Pods can stack, so area of effect is somewhat important. Attack speed is massively important in terms of DPS and enjoyment.

Recovery:

With flasks up, we sit at a comfortable 45k Evasion to cap our QOTF, and 50/75 dodge/spell dodge. This means we rarely get hit, and when we do, we proc Ghost Shroud.

Main Link

Toxic Rain - Mirage Archer - Void Manipulation - Vicious Projectiles - Swift Afflictions/Efficacy - Empower Level 4 - Efficacy

For your offhand:

Caustic Arrow - Mirage Archer - Greater Multiple Projectiles - Swift Afflictions - Vicious Projectile - Void Manipulations

Auras

Flesh and Stone - Malevolence - Discipline - Enlighten

You can grab reduced mana reservation off the tree if you want to force Blood and Sand, but I'd recommend just not bothering until you get a strong enough enlighten. You can consider running Dread Banner if you have a low enough mana cost on Toxic Rain/Caustic Arrow, but don't have Enlighten. You may also want to use a level 1 Clarity somewhere else in your gear. This will give you access to Clarity mod Watcher's Eye, and Vaal Clarity which can help with early bossing.

Wither Totem

Spell Totem - Multiple Totems - Faster Casting - Wither

We already have quite a bit of duration, so faster casting helps us build quicker.

IC + Blink Arrow

CWDT - Steelskin, Clarity - Blink Arrow - Faster Attacks - Culling Strike

I've been trying out CWDT Steelskin, and I think I like it so far. Play around with it and see how it feels. We also put Frenzy and Blink Arrow here linked with Faster Attacks and Cull. 

Despair

Dash - Second Wind - Curse On Hit - Despair - Withering Step

30 points -> 50 points -> 70 points -> 90 points -> Full

[3.12] PoE Flashback Trickster Essence Drain Shadow Cheap Build - Fast Mapping, Tankness

Gems Setup

Weapon

Essence Drain - Swift Affliction - Void Manipulation- Empower - Controlled Destruction - Efficacy

There is no variation when it comes to essence drain. You should push for a 6l as soon as possible and buy a level 3 empower. If you only have a level 1 or 2 empower but you have a 6l, you should use Decay support instead

Helmet

Vaal Discipline - Malevolence - Enlighten - Flame Dash

You should put your auras in your helmet because vertex gives +1 level of socketed gems. This means you will only need a level 3 enlighten instead of 4. It will also give a slight damage and ES boost by leveling your auras more.

Gloves

Contagion - Increased Area of Effect - Intensify - Faster Casting

If you use an es base gloves, you should put your Contagion setup here for ease of coloring. Intensify and area of effect supports are mandatory to make contagion's aoe massive. Faster casting is a nice quality of life boost.

Boots

Wither - Spell Totem - Multiple Totems - Increased Duration

I recommend placing a 3l wither totem here. Don't use blight totems, it's lower range, worse hinder and takes a jewel slot. It's a noob trap. Wither doubles our damage against anything that stands 2 seconds in the wither circle, it should be used against endgame bosses.

For your 4th socket, if you do not have aspect of the spider on a piece of gear, you should use flesh and stone in sand stance: Flesh and Stone

If you have aspect of the spider, you have a free socket.

You should put a Phase Run inside. In your skills bar, bind phase run to your left click button to trigger it automatically when you start moving.

Body armor

Here you have some choice. For more damage, the best option is blight:

A CwdT setup is also viable with the following gems:

CWDT - Summon Stone Golem - Spirit Offering - Enfeeble - Steelskin

If you do not have aspect of the spider on a piece of gear, you should use flesh and stone in sand stance

Weapon Choice

Price scale: Budget - Midrange - Expensive

This is the only piece of gear you must invest in for endgame bosses. While the rest of items you wear can be 2 chaos trash, this one is important!

[3.12] PoE Flashback Champion Earthshatter Duelist Tank Build - Cheap, Endgame, Safe

Gems Setup

Main Attack

4L (Early Game): Earthshatter - Impale - Fist of War - Melee Phys

5L (Mid Game): Add Brutality

6L (End Game): Add Close Combat or Pulverise depending on your preference/weapon. You can also play with Melee Damage on Full Life if you have manage to get some overleech.

Auras

Pride

Flesh and Stone - Maim

You can squeeze Vitality here if you want, but I rather have more mana for mobility and War Cry's.

War Cry's

Enduring Cry - Seismic Cry - Intimidating Cry - Second Wind

For last, you can choose your Mobility Skill (Leap Slam, Dash or Flame Dash). If you go for Leap Slam, make sure to get Combat Control on the Skill Tree, and attach Enduring Charge on Melee Stun or Rage for some quality of life improvement.

Defense

Molten Shell / Vaal Molten Shell - Increased Duration

Alternate Quality Gems

Anonamlous Fist of War

• Support Skills have 20% reduced attack speed.
• Support Skills deals 60% increased damage.
• According to POB, this gem can boost your damage by about 11%.

Pulverise

• Supported skills have 10% less attack speed
• Support skills have 20% more melee area damage.

According to POB, this gem can boost your damage by about 13%.

Pride

• Nearby enemies have -5% Physical Damage Reduction.

Could not check damage with POB, but basically it's free damage compared with the default version.

You can have some more quality of life changes on other gems like your, Second Wind, Molten Shell, but it's not that important, just helps a little bit more.

The Phantasmal version of Seismic Cry and Intimidating Cry seems like a decent boost of damage as well, and I don't think the 10% recovery speed will be missed that much.
