I can't even pass the 4th one, I'm nowhere NEAR ready to even try the 25th though. That's a massive jump. Maybe if I was stuck somewhere in the teens ... but I clearly suck too much, and thus I think I need a guide that explains things more.

The ones I've found have just said "spam attack spells and white wind to not die" ... and I die anyway, on the first wave of 4, most of the time. I have no clue what I'm doing wrong either.
