Torchlight: Infinite Best Erika Thunder Slash Build Guide – Afterlight Season SS13 Fast Farming Build

Summary

The Afterlight season (SS13) has reshuffled the meta, but one build stands out for sheer speed and farming efficiency: Erika 1 Wind Stalker with Thunder Slash. This guide breaks down everything you need to know to get this build running on a budget, hit high DPS, and farm endgame content smoothly. Whether you're grinding for gear upgrades or looking to skip the farming grind entirely, you can buy Torchlight: Infinite Flame Elementium from trusted platforms to accelerate your progress and get your build online faster.

1. Why Erika 1 Wind Stalker?

Erika 1 is the fastest mover in the game, and her kit is tailor-made for the Afterlight seasonal mechanic . The Night Watcher procession rewards clear speed—green lantern means more loot, red means you're falling behind . Erika's mobility and damage-on-the-move playstyle excel here.

Key Strengths:

Extremely fast movement speed — zooms through maps

Low gear dependence — functions well on a budget

Multistrike synergy — Thunder Slash naturally benefits from multistrike stacking

Scales into late game — no reroll required 

Weakness: She is fragile early. If your movement and dodging are sloppy, expect deaths through the campaign .

2. Core Skill Setup

Main Skill: Thunder Slash

Thunder Slash is your primary damage dealer. It comes with built-in multistrike chance and deals more damage on multistrike hits .

Support Gems (Recommended):

Alternative: If you want to be extra lazy, you can use Activation Mode: Medium Motionless, which makes you attack automatically while standing still. Just Spiral Strike through the map and it'll hit everything automatically.

Buffs & Auras

3. Gear Priority

This build is designed to be budget-friendly. You can get it running for around 100 Flame Elementium (FE) or less .

Weapon: Claw (or Farewell Desire)

Your weapon is your biggest damage source.

First-hand: Claw with Dexterity, Lightning, and Flat Fizz damage — Thunder Strike converts Fizz to Lightning, so prioritize Lightning over Fire, Cold, or Erosion 

Budget Alternative: Farewell Desire sword — grants +1 Multistrike, 200% increased multistrike chance, and Steep Strikes on multistrike 

Helmet

Target: Numbed duration effect + additional lightning damage. A well-rolled one can be around 13 FE.

Chest: Varbax's Heart

Very cheap (2-3 FE) and provides a massive damage multiplier. A key power spike item.

Belt

Tier 2-3 rolls with life restoration. Look for "Restore 3% life on defeat" — this offsets the life-drain downside from your weapon .

Gloves: Mark of Thrill

Provides Fervor (attack speed + crit strike chance) and makes your attacks consume no mana while Fervor is active — crucial for sustaining auras .

Amulet

Target: +1 to Agility Blessing stacks and lightning damage. Focus Blessings give 5% additional damage each — at 4 stacks, that's 20% additional damage .

Boots

Look for a cheap pair with movement speed and resists. You can even get these from early Treasure Troves.

Rings

Flat damage rolls — prioritize Fizz and Lightning. Avoid Fire, Cold, and Erosion damage .

4. Hero Traits & Memories

Hero Trait Allocation

For Wind Stalker, allocate:

Bottom → Top → Top 

Why: This path maximizes Stalker stacks, movement speed, and multistrike damage.

Memories (Very Important!)

Many players overlook memories, but they are critical for scaling.

Aim for an orange memory with two good fixed stats (Lightning crit damage, Attack/Cast Speed) 

Reroll until you get a decent random stat

Prioritize crit-related stats — Critical Rating, Lightning Crit Damage, Attack Speed

5. Passive Tree & Talents

Talent Trees

Key Notables

Hasten — attack speed

Rushed — more damage while moving

Quick Decision — faster casting

6. Core Mechanics Explained

Multistrike

This build revolves around multistrike. Every time you click, you attack multiple times due to multistrike support. Stacking multistrike chance and damage is your primary scaling vector .

Focus Blessings

Focus Blessings grant 5% additional damage each. Your amulet gives +1 to max stacks, so with 4 stacks, you get 20% additional damage. Maintain these by using Thunder Spirits .

Mark Synergy

Marked enemies take more damage—especially crit damage. Your skills apply marks naturally, and additional marks further increase the effect. This is why crit scaling is so important .

Life Sustain

Your weapon (especially Farewell Desire) consumes 1% of your life on each kill. Offset this with:

Life restoration on defeat on your belt

Life regeneration on gear 

Compound Source for emergency recovery

7. Farming Strategy: Black Sail

The Afterlight seasonal mechanic, Black Sail, is your primary income source.

How It Works

You find an unnamed coffin, light a lantern, and guide a funeral procession. Enemies chase the light — your job is to keep the area clear .

Lantern Colors:

Black Sail Strategy

Run Black Sail in Timemark 7 for consistent scraps and threads 

Use the 100% Black Sail chance node on your passive tree

Skip Whisper nodes at this stage 

Veteran's Coffins have tighter timers but better loot 

8. Budget Breakdown

9. Progression Checklist

Leveling: Use Thunder Slash from level 1 — it's Erika's starting skill

Farm Black Sail for consistent currency

Save for Weapon Upgrades: Full T1 mods when you can afford them
