Intelligence Reports

Intelligence Reports were added to TERA in patch 85 in August 2019.

You need to find two pieces of Intelligence Report (left and right half) and combine them. This reveals location where you'll find Suspicious Wagon. Gather a party of five players and use the report near the wagon to activate event.

Intelligence Report pieces drop least in dungeons, and possibly from open world monsters. Originally: Initially report parts could only be traded by putting them in Guild Bank. They can be traded between players now, but not on trade broker.
 * Dungeons of item level 435-445 drop left parts of report.
 * Dungeons of item level 446-456 drop right parts of report.

There are ten possible different locations where Wagon can be found. Locations are listed in Achievements->Encounters and Exploration->Miscellaneous->Fire Bad!. Note that only player who activated the report gets achievement.

After Intelligence Report is used, event starts. Number of Nagas spawn, lead by Naga Captain. Defeat the enemies. They drop Essence of the Nexus II potions that give 250 million XP each and Naga Captain's Belongings that has some jewels (usually least one Diamond).

This is quite similar content like Naslow's Treasure Maps and made to ease leveling 65–70. Changes to Macellarius Catacombs in April 2020 made this content pretty much irrelevant. MC now drops more XP potions than Intelligence Report hunt. Reports have not been seen dropping after patch v102. Maybe they were silently removed.
