Portal Knights: How to Farm Energy Crystals and Every Crafting Recipe

Portal Knights treats Energy Crystals like fancy currency: scarce, traded for the best loot, and weirdly absent from the first dozen hours of play. If your goal is endgame weapons, relics, or top-tier armor, a steady supply is non-negotiable. This HolyHosting guide breaks down where to find them, which fights are worth your time, and exactly what they craft.

Where Energy Crystals Come From

Energy Crystals drop from a handful of reliable sources: enemy kills, event minibosses, summoned bosses, chests, and the rare quest reward. Killing the right targets in the right places is the consistent path. Hoping for chest RNG to feed your crafting bench will leave you waiting forever.

Event Enemies Worth Farming

World events spawn dense groups of monsters that drop Energy Crystals at noticeably higher rates than the open world. A few, like the Araktula Invasion, even work below level 25, which gives lower-level characters a useful head start on the loot ladder.

These are the enemies to focus on:

• Baby Araktula: Araktula Invasion
• Bamboo Araktula: Araktula Invasion
• Striped Araktula: Araktula Invasion
• Thunderstorm Crystal: Electro Thunder Storm
• Rainstorm Crystal: Tropical Rain Storm
• Sandstorm Crystal: Sand Storm
• Snowstorm Crystal: Snow Storm

The Tomb of Ch'Thiris

The Tomb of Ch'Thiris is the closest thing the game has to a dedicated farming dungeon. Entry requires a C'Thiris Tesseract, which itself costs 1 Energy Crystal plus 10 Stone Blocks. Yes, you need an Energy Crystal to grind for Energy Crystals. Plan accordingly.

Once inside, anything destructible is fair game. Enemies, tombstones, and coffins all roll on the loot table, so destroy everything in sight. Enemies inside hit harder than typical overworld mobs, so do not visit below level 24 unless you enjoy long walks back from spawn.

The drop rates are excellent and the island is fully repeatable, which makes it the most efficient long-term farm in the game. Just keep at least one crystal in reserve so you can build another Tesseract for the next run.

Summoned Bosses

Summon bosses can also drop Energy Crystals, though the rates are inconsistent. They work better as a side activity than a main strategy. Each boss has a minimum level requirement before crystals enter the loot pool:

• Slime Queen: summoned with the Slime Queen Amulet of Invocation, level 14+
• Knight Hunter: summoned with the Knight Hunter Amulet of Invocation, level 25+
• All Watcher: summoned with the All-Watcher Amulet of Invocation, level 30+
