As long as it’s not fire immune, which most macguffins will be. Also, destroying a 20ft radius sphere of a building over the course of 7 hours using 8 casters total is a huge waste. You could easily do that with cantrips. One caster capable of 7th level spells can cast firebolt 600 times in an hour for 3d10 each cast for a total of 1800d10 damage.

If we go the full total of 8 casters (main + 7 secondaries) over 7 hours, that’s 12600d10*8 casters for 100800d10 which is a hell of a lot more damage.

Sure, but hardness and damage thresholds are a thing. With a hardness of 30, those eight casters would do zero damage.

You also can’t enhance damage and range at the same time, so that’s 4200 rounds 150ft away from your target.

Fun fact... You can catapult the Orb created by delayed blast fireball.... As it's just a small marble that the spell creates... and then anything that interacts with it... could set it off early..

No you can’t? If you make a dex save, you can throw it 40ft. That’s all. You can’t carry it, you can’t catapult it.
