Rain of Arrows can feel powerful long before it becomes reliable. The real test is whether your Rogue can cast it again before a fight moves on. Start by checking the cooldown and energy numbers on your own character, rather than chasing a damage target from a build description. Gear choices, seasonal changes, and skill interactions can all affect the result. If you're still gathering equipment, D4 items may help you explore options, but the setup itself needs to work with the current version of the game.

Check the Cooldown Before Chasing Damage

The proposed loop depends on two things lining up: a short Rain of Arrows cooldown and a large energy spend. Preparation is commonly described as reducing an Ultimate's cooldown by five seconds for each 75 energy spent. On that basis, spending 300 energy could return up to 20 seconds. Treat that as a target to test, not a guarantee. Your effective cooldown has to be low enough for the refund to make another cast available, and the relevant effects must still work as expected in the current season.

Make the Energy Spend Repeatable

Beastfall Boots are central to the suggested approach because they spend available energy when you cast an Ultimate. That can create a large Preparation refund, but it also leaves you needing energy for the next cast. The article's proposed answer is to stack Rain of Arrows ranks and rely on an energy-restoring effect called Epilogue. Before building around it, check that the effect is available and confirm its actual wording in your version. A tooltip and a quick test are more useful than assuming a high rank count will refill the whole pool.

Choose Gear for the Job

Cooldown Reduction on usable gear slots is a sensible place to begin. Masterworking may improve key affixes, while skill ranks and maximum energy can support the loop. Keep an eye on the trade-off: a piece that helps the cooldown may offer less survivability or damage elsewhere. Names such as Crown of Lucion, Dark Shroud, Cold Imbuement, and Caltrops suggest different roles in the build, but they don't all solve the same problem. Check each item and skill in your current setup, then keep the pieces that help you cast often without leaving the Rogue too fragile.

Test the Full Rotation in Real Fights

Try the sequence on a durable enemy before taking it into a demanding dungeon. Watch the cooldown, note how much energy Beastfall Boots consume, and see whether you have enough energy for the next cast. If the loop stalls, adjust one part at a time instead of replacing the whole build. U4GM offers a convenient platform for buying game currency or items, and you can browse u4gm D4 items when you're looking to fill a specific gear gap. Then test the change in combat and keep what genuinely improves the rotation.
