It does not matter what event. As long as you possess any ever so slightly demanding sealstone, you'll be sucked dry. Yeah, regardless of your lead too (exception maybe bell lead). Trust me, I'm at level 100s with Kaguya lead and I get attacked every time I level up or possess a ss. I get heaps of silver from countering until some1 monstrous or lucky beat me.

So if you're concerned about event achievements, SG might be the best since it's the most worthless event. So it doesn't matter if your progress is intereferred.

If you're concerned about ss completion, do them all before entering 81. I had like 20 blue and purple from tomomds back in level 80 with over 6 charms on each and Minerva lead. Lost all of them in 1 misclick. So there you have it.
