Rune of Shaping: Rerolls the implicit stats of an item (the properties at the very top). Particularly valuable on Last Epoch gold weapons like daggers with high crit multiplier ranges.
Rune of Ascendance: Upgrades a base item into a random unique of that type. With the Circle of Fortune faction, you gain a chance to preserve your runes, making this an efficient way to farm build-defining uniques.
Rune of Weaving: Instantly progresses the Weaver's Will mechanic, saving you the time of equipping and leveling the item manually.
Rune of Havoc: Shuffles the tiers of affixes. This is where advanced crafting shines-by sealing or adding low-tier affixes, you can attempt to move a T7 affix into a more desirable stat slot.
Rune of Redemption: Randomizes exalted affixes on an item. A gamble, but it can turn bad double exalts into something usable.
Rune of Creation: The rarest and most powerful rune. It duplicates an item but sets the forging potential of both the original and the copy to zero. It's essentially a way to "mirror" a perfect exalt, giving you two chances at slamming it into legendaries.
Crafting Strategies
Early Game: Use runes of discovery to fill out gear and glyphs of hope to stretch FP. Don't worry too much about perfection-just aim for solid defensive and offensive stats.
Shard Farming: Shatter most rare items you won't wear to build up shards. Use removal sparingly for hard-to-find affixes, especially on low-affix blues.
Exalt Preparation: Always save high-tier exalted items, even if the affixes aren't ideal. They can become the foundation of a legendary or be manipulated later with glyphs and runes.
Advanced Crafting: Combine glyphs of despair with runes of havoc to attempt tier shuffles, or use refinement to maximize top-end rolls. Be prepared to fail sometimes-crafting in Last Epoch always involves risk.
Endgame Perfection: If you ever find a god-tier exalt with your best stats, be patient. Save it until you acquire a rune of creation so you can duplicate it before committing to a legendary slam.
Idol Crafting
Class-specific idols can also be enchanted. Running Monolith echoes like the Cemeteries allows you to cheap Last Epoch gold apply an affix and Weaver's Will to idols. Just like weapons or armor, you can accelerate the process with runes of weaving or reroll undesired outcomes.
