From Modrinth

A mod to make building in main end island more feasible.

There are 3 gamerules included in the mod

disable_dragon_grief - [true/false] - disables the dragon breaks blocking
end_pillars_griefType - [REPLACE_AIR / REPLACE_NOTHING / VANILA] - determines what blocks will be removed/replaced in the end pillar generation/regen
end_crystal_explosion - [NONE / DESTROY / BREAK] - determines what kind of damage the INITIAL SPAWNING EXPLOSION of end crystals cause. NONE will only cause damage to entities, BREAK will drop all the blocks, while with DESTROY only some of the blocks will be dropped as items.

End Pillar generation features will only affect regeneration of them when respawning the dragon. It will not the affect initial end generation.
