While its cool that consecrated ground can stay forever when cast I feel like there should be a way to remove these areas or limit the spell to only consecrate temporarily. In home areas I love having the consecrated ground as I can stay healed and full forever without the fear of mobs entering my domain but out in the wilderness, in boss battles or just area restructuring like adding a mob farm these areas can get in the way and or provide advantages for others that were not intended.
E.G. if you consecrate an area in the end when fighting the ender dragon then the next players to fight the dragon can stay in this area without so much as armor to keep them safe when fighting tilting the balance of progression for other players

You can currently remove Consecration fields by placing a solid block at the field's location. The field won't be there anymore if you subsequently break the block. Is this satisfactory, or did you have something else in mind?

So the solid block placement is not in the grimoire which is why I thought it was permanent, as a start it would probably be a good idea to add it in there. As an alternative maybe shift right clicking with a wand that does not have a spell selected?

The above though does not address the issue of creating an unfair advantage for other players in endgame/boss situations. What about for the consecration spell if you have an extra option for the spell to make a temporary consecration or permanent much like how you can add silk touch to the break spell with a 1 or a 0
