You only need to know the regular parity alg (just not lucasparity), and you could learn some last 2 edges cases, but you can solve those with just slice flip slice backs and the parity alg if necessary. I average 2:30 and I don't know a single one of them, so you can get by without them.5x5x5 parity and must know 5x5x5 algs to solve the 5x5x5 well
also you may want to use a commutator for the last 2 centers, just look it up on YouTube, it's really simple. Just a niklas but using different slice moves.
