Escudo

The Escudo (エスクード) is an Optional Trigger. It is a defensive trigger but can also be used to create an obstacle to hinder enemy movement or even trap enemies between its walls.

Description
This trigger forms a blocky wall-like structure that sprouts from the ground, a wall, or other surface. It has the Border logo prominently displayed on its face. It resembles a crenelated wall of a medieval castle.

Abilities
Escudo is a defensive barrier that has more toughness than a normal shield. It also acts as a structure and obstacle. Its drawback seems to be that it is immobile. It can also be used to trap opponents, as demonstrated by Yūichi Jin.
