If you've ever wondered how to craft and slam the most powerful, whether you're aiming to build your dream Lich setup or perfect a Paladin's relic, we'll cover the entire process: what to look for, how to craft efficiently, and how to slam your item for maximum potential. Having a lot of Last Epoch gold can also be very helpful.
Understanding What You're Crafting
Before you even start crafting, know exactly what you're trying to make. For example, let's say you're building a Lich and want to craft the perfect offhand using the Stygian Coal. The goal is to combine a Stygian Coal with Legendary Potential (LP) and an exalted item that has your desired affixes.
Each LP represents how many affixes from the exalt will transfer over when slamming. A 4 LP item can absorb all four affixes, while a 2 LP item can take two. The more LP, the greater your potential to create a true god-tier item.
Step 1: Picking the Right Base Item
Started with a 2 LP Stygian Coal and a catalyst that had T7 crit multi - one of the most desirable stats in the game. The goal was to transfer that T7 crit multiplier into the unique through the legendary crafting process.
When looking at an item, consider two main things:
Affixes - Do you have the stats you actually need?
Forging Potential - The number of times you can safely craft before the item locks.
If your forging potential hits zero, you can't modify it further. However, if your item is close to perfect, you can use a Rune of Creation to duplicate it, giving you two shots at slamming for the perfect Legendary.
Step 2: Start Crafting
Begin by adding or improving the affixes you need. For example,  Added spell crit to complement the existing crit multi. Always use a Glyph of Hope while crafting to minimize the loss of forging potential with each upgrade attempt.
If your best affix is sitting in the wrong slot, use Runes of Havoc to shuffle tiers around. This process is risky but can produce miraculous results - like moving a T7 crit multi onto the perfect prefix slot.
Sometimes you'll completely miss and ruin your item. Other times, you'll hit what calls "the miracle" - the exact roll you wanted. Accept that luck is part of Last Epoch's crafting philosophy.
Step 3: Decide What to Upgrade
Once you have the correct affixes in place, focus on upgrading the ones that matter most. In the Lich example, prioritized crit multi (for pure damage) and spell crit.
However, every upgrade consumes potential. If an upgrade could consume all your remaining potential, consider safer plays, like upgrading a resistance stat that only costs 1-10 potential points. Balancing risk versus reward is the heart of endgame crafting.
You can also seal an unwanted affix to make room for a new one. For instance, sealing off cold resistance lets you craft void resistance in its place. Sealing does not prevent you from slamming - it just hides that affix from the fusion process.
Step 4: Fine-Tune with Rune of Refinement
When you're nearly done, check your key stats' values within their roll range. If your crit multi rolls mid-tier (say 52 out of 58), you can use a Rune of Refinement to reroll it to a higher value - if you have potential left.
Refine only the stats that are guaranteed to transfer during the slam. Don't waste resources perfecting affixes that might not move over.
