Heart of the Enemy

Daily: Heart of the Enemy is a daily quest and achievement/trophy in Fallout 76.

Quick walkthrough
The Brotherhood of Steel was looking for weaknesses of the Scorchbeasts. It involved Mission 099-01, which requires going to Vault-Tec University and wiring up one of their Automated Research Labs to find the weaknesses of the Scorchbeasts.

Detailed walkthrough

 * This daily quest becomes available after completing Recruitment Blues and gaining access to the upper floor of Fort Defiance. Find Mission 099-01 orders in Fort Defiance in a folder on a dresser in the bedroom next to the kitchen on the fourth floor.
 * Then go to Vault-Tec University. The automated research lab requires power. To provide it, the player needs to find the generator room, hack the power terminal, and select the option "Allocate Power to Automated Research Lab".
 * Then, activate the Automated Research Terminal and choose "Execute Automated Test". The terminal indicates it needs a fresh scorchbeast DNA sample.
 * The scorchbeast will be spawned within the region of Cranberry Bog by the quest. Completing Line in the Sand can help kill one. If you're lucky you can just loot the DNA from a dead scorchbeast that has already been killed by another player.
 * To complete the quest, place the sample into the Automated Centrifuge. Then go to the research terminal and select "Execute Automated Test"
