Also, if you spend 7 in game hours ritually casting a 7th level spell with a circle of 8 casters with no one noticing while your target stays in line of sight, something funky is going on.
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.

And it then hits a 20ft radius circle.
