The Legend of Heroes: Trails of Cold Steel

Combat Links are a core game mechanic. Once you unlock them during your first Free Day trip to the Old Schoolhouse in April, you should always keep your characters linked in battle. Every time you Unbalance an enemy, you'll be given the option to have the linked character perform a follow-up attack to assist.

Your third visit to the Old Schoolhouse, in June, will unlock the Rush linked attack. In order to perform a Rush, you must build up bravery points by performing Assists first. Once you have 3 points, the Rush attack becomes available during the cut-in - just press . This will consume your 3 points and perform the attack, allowing both linked characters to get in an extra hit, and allowing multiple enemies to be targeted if they're close enough to each other. Do this 100 times, and the trophy is yours.

Note that, initially, you cannot store up more than 3 bravery points even if you continue to do standard assists, so unless the enemy is all alone with only a sliver of HP, you should generally prioritize using Rush over Assist.
