Guard Block is a block that is craftable in the Engender Mod.
Crafting[]

In order to make a Fusion Crafter, the player needs four Iron Ingots, four Iron Bars, and one Diamond and they need to place them as seen in the picture in a Crafting Table.
Usage[]
Placing the block on the ground will cause it to release the particles that are used for End Rods and Enchantment Tables, and the block itself emits a light level of 14. Right clicking on the block when you have tamed Engender mobs next to it will cause those mobs to guard in a 32 x 32 block area around the Guard Block, and they will no longer attempt to follow or teleport to the player, unless the player shifts and right clicks that mob. This block is good for keeping certain mobs in a certain area, such as keeping Undead mobs in a shaded area to avoid direct sunlight, or keeping weaker but powerful support unit mobs like the Villager or the Eversource in a safe area away from enemies. The mob and player will be teleported back if the player attempts to mount the mob and ride away from the Guard Block, and using a Carrier to bring the mob away from the Guard Block will result in the mob being teleported back on its own.
