The Legend of Heroes: Trails of Cold Steel II - Shining Pom Bait Set #4

Civil war has broken out across Erebonia. After his narrow escape from Trista, Rean will take up his sword again on a journey with his Divine Knight, Valimar, in search of his friends from Class VII and a way to end the conflict before its price becomes far too dear...

This DLC includes:
Shining Pom Bait Set 4

This set contains 3 consumable baits that, when used, will lure out an elusive Shining Pom. Defeating these rare creatures in battle will reward a massive amount of EXP, helping your party reach new heights. Once used, they will disappear from your inventory.

This is set 4 of 5. Each of these packs contain the same 3 consumable items to help you level up.
