WHERE & HOW TO FARM Where to farm Phase Beast portal in Frosted Hills when the crystal-defense challenge is selected.
The Frosted Hills crystal-defense challenge rewards blue chests for crystals that survive the encounter. The practical goal is therefore to defend the crystals rather than simply maximize kills or rush through the room. The challenge only appears if the Phase Beast opens that portal from its area pool, so this is a targeted activity once you receive the draw, not a guaranteed challenge you can select. Collect the earned chests after the defense and compare their loot with your current gear.
Before you go Reach Frosted Hills and find a Phase Beast. Receive the crystal-defense challenge from its portal draw. Bring a build that can handle the challenge enemies and protect objectives. Defeat the Phase Beast and enter the challenge portal. Identify the crystals and the enemy approach before engaging. Stay near the objectives and attack threats that endanger the crystals. Use area damage carefully so you can control enemies without abandoning vulnerable objectives. Finish the defense and check which crystals survived. Collect the blue chests earned for protected crystals and inspect their contents. Farming tips Defend the crystals first; the reward is tied to the crystals protected. If the Phase Beast opens another challenge, complete or leave it and wait for another beast rather than expecting to choose this one. Repeat, collect and use Repeat only when the randomized Phase Beast draw produces this challenge again. The challenge is not guaranteed on each visit.
Common mistakes Chasing enemies away from the objectives and allowing crystals to fall; keep threats near the crystals prioritized. Leaving before claiming earned blue chests; inspect the challenge area after the defense. Assuming every Frosted Hills portal is crystal defense; the activity is drawn from a pool. When to stop or switch End the run after collecting the earned chests, or abandon the defense if protecting the objectives is no longer feasible.
