Shield o' Light and the Totem of 13

This post is an add-on to the post "Lava based mob in the Overworld", so read that before this one.

The Shield o' Light works by putting the vanishing curse on it. it will no not be visible to the person holding it, but exposes a huge amount of light to other entities, and can burn mobs. It will also kill mobs in a 100 block radius for a drop of one rooted dirt block.

The Totem of 13 will kill the entity holding it in 13 game ticks. The only way to hold it for longer is to have a totem of undying in the other hand.
