A mod developed simply so that I can add all those random things I want when I use Blood Magic, such as an Mob-Spawning ritual, or a Sigil that uses a large amount of LP to make a large mining tunnel, or a Sigil to swap one kind of block in the world for another, or Ritual Stones that can be hidden behind covers, and still work. My personal favourite are the Warded Ritual Stones.
If you're thinking "haven't I seen some of these functions before?" you have. I just wanted some that ran on LP, so I made them without looking at how others had made theirs. If you want to look at my code, it is available in the Source tab above.
