Because this character is different from other characters, you need to see monsters before attacking (except the bow horse)

You can imagine yourself as a place where people set traps. There are some pictures for reference. Never mind that they don't draw well;

Figure 1: The character is in the middle of the current screen, and the trap can be left at the edge of the screen. The trap will attack all monsters within one and a half screens of the character.

Figure 2: When there are obstacles, other characters have to face the attack directly, but assassins can take advantage of the particularity of trap attack methods to "fight monsters from afar"

Summary:

Encountered a large group of monsters, 4 Lei Guang+1 Undead, rhythm control, left hand flame detonation, right hand switch trap.

When you meet boss, five thunder lights are put away, and the left hand flame explodes and throws it at boss.
