I am trying to make a custom item, which i succeded in, but now i am trying to figure it out how to make it give u 5 extra hearts, and 0.5 extra attack speed when holding in your offhand. I read the wiki but it just says the template for adding attributes and i dont rlly understand.
Also, this is not as important but when i try to add a tooltip for my item, when hovering over the item it shows the name, then it says "KubeJS" then it shows the tooltip, how do i fix that.
