Warden "Burrows" After Targets

With the Warden both arriving and leaving by burrowing it would make sense for it to use this ability to chase its targets. This could work similarly to how Spiders climb blocks only on the inside instead of/in addition to the outside. The sonic attack helps, but it is still possible to just pillar too high or wall it off and move out of range. Players can then casually shoot the Warden or leave it to prevent more from spawning. If this is too powerful it could be balanced by making it only do this during the chase, having it move slower through blocks and/or making it unable to pass through (though possibly still climb on) certain blocks. Players could then try to evade or slow down the Warden to outrun it. This would make angering the Warden actually threatening without making it an automatic death sentence. It should prevent any players who aren't specifically going out of their way to kill a Warden from realistically doing so.
