Crafting the best gear in Last Epoch can be intimidating - exalted tiers, legendary potential, forging potential, and the mysterious "slam." But once you understand the process and the logic behind every decision, creating your dream endgame gear becomes one of the most satisfying parts of the game. Sufficient Last Epoch gold will help you build equipment.



This guide walks you through how to craft, optimize, and slam your items, using practical examples and the same mindset top crafters use.



Step 1: Understanding Legendary Potential and the Goal



In Last Epoch, the foundation of every legendary item is a unique item with Legendary Potential (LP). The number of LP (1-4) determines how many affixes from an exalted item can transfer onto your unique when you "slam" them together in the Temporal Sanctum dungeon.



For example, if you have a 2 LP Stygian Coal, you'll be able to merge two affixes from an exalted catalyst into that unique item. The goal is to carefully plan which exalted affixes you want - usually the highest-tier offensive stats for your build, like Critical Strike Multiplier or Spell Critical Strike Chance.



Step 2: Picking the Right Exalted Base



Before you even begin crafting, identify what you're trying to make. In Rex's lich build example, the focus was on a catalyst with Crit Multi and Spell Crit as prefixes, and Void Resistance and Elemental Resistance as suffixes.



High-tier prefixes (Tier 7 ideally) should always be your priority since they provide the biggest power boost. Suffixes like resistances can be added or adjusted later, depending on your available forging potential.



Step 3: Managing Forging Potential



Every craft reduces your item's Forging Potential (FP). When FP hits zero, the item can no longer be modified.



To preserve FP:



Use Glyphs of Hope while crafting to reduce the chance of FP loss.



Stop crafting once you reach strong affix tiers - you can always duplicate the item with a Rune of Creation to get another attempt at perfection.



If your FP is still high after good progress, you can safely refine or upgrade additional affixes.



Step 4: Shuffling and Perfecting Affixes



To manipulate where your high-tier affixes land, use Runes of Havoc. Havoc shuffles the tiers of existing affixes, potentially moving your T7 affix to a desired prefix or suffix slot. It's risky, but crucial if you want to maximize your item's potential.



For example, if your T7 Elemental Resistance lands on a suffix you don't need, using Havoc might move it to Crit Multi instead - which is exactly what you want.



Once your ideal stats are aligned, you can refine the item further with Runes of Refinement, which reroll the values within a tier to try for perfect rolls.



Step 5: Strategic Sealing and Upgrading



If you need to open up room for new affixes, you can seal a low-tier affix. Sealing removes it from the main pool but still keeps its benefit active, allowing you to craft something new in its place.



Contrary to some player myths, you can slam an item with sealed affixes. The sealed affix just can't be chosen as one of the transferred ones - but that's fine since sealed affixes are usually lower priority anyway.



When upgrading, always evaluate the risk vs. reward. If you're about to spend a large chunk of FP upgrading a minor stat, it may not be worth losing the ability to duplicate or refine the item later.



Step 6: Preparing for the Slam



Once your exalted item is finished, it's time to merge it with your unique.



Before slamming:



Make sure you've crafted your unique LP to have the right one.



Confirm which affixes are most valuable - remember, you only get as many transfers as your LP allows.



Duplicate your crafted exalt if possible, giving yourself multiple chances to hit your desired combo.



The goal is to ensure that your guaranteed and highest-impact affix (like T7 Crit Multi) will transfer over, and then pray for good RNG on the rest.



Step 7: Entering the Temporal Sanctum



To slam your items, you must enter the Temporal Sanctum dungeon using a key. The tier you choose determines which item levels can be fused:



Tier 1: Low-level items only



Tier 2: Up to item level 65



Tier 3: Up to 75



Tier 4: No level restrictions



You'll face the boss, Julra, at the end of the dungeon. Survive her attacks (you can switch realms with the "D" key to avoid damage) and reach the Eternity Cache to perform your slam.



Always run at least Tier 2, as this guarantees one affix of your choice will carry over.



Step 8: The Slam Itself



At the Eternity Cache:



Place your unique with LP and your crafted exalt into the interface.



Choose which affix will guarantee transfer.



Confirm and complete the merge.



If luck is on your side, your exalt's perfect T7 Crit Multi and Spell Crit roll onto your unique, creating a truly powerful legendary. If not, that's why you used the Rune of Creation - to have another shot.



Step 9: Example - Crafting and Slamming Boots



Boots are simpler. You usually want Movement Speed, Cooldown Recovery, and Hybrid Health. With buy Last Epoch gold only 1 LP, you only need to guarantee one crucial affix - typically Movement Speed.
