Jamie Ann Robyn reporting for duty! There aren't many changes to Jamie's design as of now. The only update is the Power Bat that she uses. The foundations of the weapon are there, but there are some little changes.
Unlike Sadie's Rook that is more hidden and defensive. The Power Bat uses a different and more direct approach to using the STAB. It uses the elements as it is for extra damage. The most common practice is to use Stan. However, Jamie likes to use other aspects to heighten her melee skills.
At the handle area, there is a bandage warped with stray edges. The bandage is dyed with the element from the previous post. The Tide Dye. Acting like an elastic rope, where Jamie can grab on. Expanding the weapon's range.
The gold ring at the end acts as a counterbalance for Jamie to make big swings. Stan users are normally straightforward. They use their weapon like normal, and because of the abundance of Stan crystals. It's very easy to refill.
