Level up with any extra sp between levels. Knight gold players should probably be able to max it at early 70s.Strategies/Tips: none really, just don't be selfish and forget to buff your party members. When there are multiple archers in your party, I would consult with each another to see whose Wings of Protection is higher level, so that he/she can give the party a better dodge/speed boost. Hell Path: 50% dodge, 20% movement speed. More evasiveness for Pap to dodge the BMs/BARs, Heaven only offers longer time duration, but wings of protection uses little mp anyhow, and 30 min/10 min is already good enough. Because repulsing is used almost every Pave battle, there is a good chance to help boost vigor up. 2 second cool down reduction for heaven isn't needed as 2 repulsing per battle is a rare event.
