The basic attributes were augmented too little, making it very easy to be targeted and extremely easy to be killed in one shot.
Even for Shen Yurou, the Mecha she created was not placed into an equipment slot but in a space slot as an item!
This is also an additional ability of a Fourth Order Mechanic: peripheral equipment loading, which doesn't occupy an equipment slot, effectively granting an extra equipment slot.
The attributes of this peripheral device could be stacked onto the attribute panel, but only one peripheral device's attributes could be activated at a time.
The equipment used by Shen Yurou herself was one of the harvests from the Undead Disaster, a complete set of Purple Epic armor with balanced attributes, with all three basic attributes nearly at equilibrium and also breaking the ten-thousand mark.
With an ultimate Mecha as peripheral equipment loading, just in terms of physical damage, she would far surpass others.
