Shiyu Defense Gameplay Guide

How to Play Shiyu Defense

1. Defeat Enemies Completing Objectives
2. Nodes: Different Types of Stages
3. Deploy with Boosted Attributes
4. Follow the Special Rules
5. Complete the Challenge Targets

Take Down Enemies While Completing Objectives

Shiyu Defense is a game mode where you must take down enemies while fulfilling objectives such as completing it within a time limit or clearing the stage with as few character knockouts as possible.

Nodes: Different Types of Stages

Shiyu Defense has three Nodes, Stable, Disputed, and Critical. The Stable and Disputed Nodes are one-time clear stages and are permanently available while Critical Nodes reset and get updated on the 1st and 16th day of the month.

Deploy Teams With Recommended Attributes

The Recommended Attributes for the Node will also be shown so make sure to make teams with Agents of those attributes to take down enemies faster.

You can also view the Node's Enemy Resistances to learn which Agent you shouldn't use to tackle the stage.

Two Teams at Seventh Frontier

Starting at Stable Node: Seventh Frontier, you must build two teams to enter the challenge and clear the stage.

Follow the Special Rules

In Shiyu Defense, each Frontier has special rules to help your Agents take down the enemies. Use these rules to your advantage and build your teams around them so you can clear the stage more easily.

Node Challenge Targets

Each Node has challenge targets that give you a rating when you complete them. These are broken down into S, A, and B ratings. Getting an S rating means getting all the rewards from that Frontier.

Shiyu Defense Tips

• Frontier Effects are For Endgame
• Inter-Knot Lv. 50 is Recommended
• Other Tips

Frontier Effects are For Endgame

Though some frontier effects would require you to use teams of certain attributes, we recommend not following them in the early game. The goal is to complete the stages, so you can just finish them with at least 1 star and go back to them once you have built a better team suited for the stages' effects.

Inter-Knot Lv. 50 is Recommended

To more comfortably clear Shiyu Defense, we recommend leveling up to Inter-Knot 50. At this level, your characters can be leveled up to the max level of 60 so you can take on all stages in Shiyu Defense.
