Day 5 of Immersive Tactical Drill highlights Quick Assists and takes Ice off the table. For easily triggering Quick Assists, it is imperative that you have at least one Support unit in the party.

Seth is an exception as he can trigger Quick Assists despite being a Defense unit, albeit to the character before him. To maximize his Anomaly buffs, you should put an Anomaly character to the left of him in the lineup.

Trial Team Rotation

As for the Trial Team, both Nicole and Seth will be able to trigger Quick Assists very easily. Should you wish to complete the objective in record time, using the Trial Team will be in your best interest.

However, do take note that Nicole will be the odd one out in this team with her Additional Ability inactive, as her party member requirements will not be met by either Jane or Seth.

How to Beat Reinforcement Operations

Immersive Tactical Drill Day 5 Guide

• Use Supports Often
• End Chain Attacks with Supports

Use Supports Often

An objective for Day 5 is to trigger Quick Assists 5 times. To make this easier for you, start with a Support unit, or any unit that can trigger Quick Assists like Seth.

Simply use the skills that they have that can enable Quick Assists. You should have no problem reaching the required amount of 5, even before the Elites start showing up.

End Chain Attacks with Supports

A neat thing about Day 5's Combat Buff is that after triggering a Quick Assist, the next Quick Assist you trigger will be replaced with a Chain Attack!

To take full advantage of this, end your Chain Attacks with a Support unit while the Combat Buff is active to initiate another Chain Attack to maximize your DMG!
