Adds Alter's tail as a craftable item to allow you to create void passages through blocks.
Usage
While holding Alter's tail in your main or off hand, aim at a block face and right click to create a portal in the direction of the targeted face. If a portal is facing downwards it will create a void string up to 10 blocks below the portal. Right click the string to teleport up the portal.
Placing Conditions
Certain blocks will not allow void passages to be created on them or the side of the block they are attached to. This includes plants, liquids, and generally blocks smaller than a slab with some exceptions such as carpets, fences, doors, etc. Grasses will get replaced by the passages and strings but other blocks that are considered invalid starts will add to the placement distance check. Bedrock, barrier blocks, and end portals and frames will prevent the placing of passages entirely.
