Masteries Required for Map Completion?
Not 100% sure for Dragon’s Stand, but the other three are really just Gliding (updraft rank 2), Itzel (Poison Lore rank 4), Exalted (Acceptance rank 2) and Nuhoch (Wallows rank 2).
Updraft and Poison Lore are the most important. Exalted is just to get I think 2 things on AB, and Nuhoch a couple in AB and TD.
I don’t know if you need the final rank of gliding for Dragon’s Stand because I’ve never been in a map that completes the meta to actually get to many of the map stuff.
Which map requires the least to finish? I’m after the class specific cache things you get for finishing a map
Some require masteries, although a couple of those can be bypassed with a friendly mesmer. The key-line one on the west side of AB. A couple points require KL in DS. Two require poison in Tangled. VB is the only one that can be done without masteries i think.
