Wonderful suggestion. I agree with @Pringle - tone down that pserver shading (3 shades for the trap and 2 for the flame is all you need) and the stun is okay.
I also find it refreshing that the name, sprite and lore do not directly point out the in-game usage and effects of the item. I don't recall seeing any such custom items but I feel like that'd grind my gears.
he can have more shades than that, depending on if he uses more colors.
I saw multiple people claiming GalaxyVolt was a scammer, but I've never traded with him. Just be wary. In addition, Hydroxide is also a scammer (scammed me out of only 2 prod life, so not much but still), so keep an eye out for him too.
