Could stop at Snape onwards, hard stop at Voldemort.
LMAO at ppl saying he can go past Voldy. Voldemort had an even fight with A LOT more powerful version of Dumbledore WHO HAD THE ELDER WAND.
Grindelwald lost to a much younger and less experienced Dumbledore even though he had EW on his side. He is leagues from Voldemort and ppl should really be able to see it by now. I honestly believe prime Snape would be a challenge for Grindelwald, and a duo vs Minerwa and Lucius will most likely end in him getting stomped.
