History of Flawless Execution

Overview

Flawless Execution is a Triumph worth 10 points. It asks for completing a Heist Battleground on Legend difficulty without dying. It belongs to the Heist Battlegrounds triumphs introduced in Season of the Seraph, and it is not one of the nine triumphs required for the Seraph seal.

How to complete

1. Queue a Legend Heist Battleground. The playlist version is reported as harder than the standard one, with enemies about five power levels above yours, so Legend should be taken with a prepared fireteam.
2. Bring a weapon that can stun Unstoppable Champions and the right artifact mods before the start.
3. Break line of sight with Seraph towers. A tower that holds you in view for 15 seconds kills you instantly.
4. On Europa, kill Deathtongue Choristers before they reach the Hive totems. While one touches a totem your abilities are disabled.
5. Use the PDT Refraction Cores on the room edges to break the Hive runes on the vault door.
6. In the final boss fight, deposit five Arc orbs at the central pylon when the shield appears, and keep your Super for the miniboss.

Tips

• Solo runs of the Moon version on Legend exist, which shows the route can be done alone.
• Heal between waves and use finishers or kills for ammo, since a single death ends the attempt.

Rewards

The triumph grants 10 points. Completing the activity drops its own rewards, which guides describe differently (see the Heist Battlegrounds page).
