BANG!
The attacks of the Diamond Golem are slow but very heavy that even Sigma who has a very high amount of defense is having a hard time dealing with it. Her defenses are high enough but it's not high enough to continuously tank damage coming from the Diamond Golem. The others are looking for chances to get close to the Diamond Golem's head but they are always being interrupted by the golem itself.
Sigma is the one tanking the damage dealt by the diamond sword, but they can't do much against the shield. It might not be as strong as the sword but the damage it inflicts is still quite high that even Hagane and Iron are having a hard time keeping their HP high enough. Not only that but they also notice that the durability of their shields is getting chipped every time they tank the damage from the shield.
