New to D2, how do I do master difficulty on onslaught

[rain prawn]

not sure if I am being stupid but I can't figure out how to start onslaught on master difficulty.

[dapper steppe]

if ur new to d2 ur not gonna be able to do legend onslaught

[rain prawn]

for future reference then

[dapper steppe]

gotta go to shaxx in the new social space, talk to him, do normal onslaught till wave 10 or sum and then u gain access to legend

[rain prawn]

is it just doing legend to wave 50?

[dapper steppe]

no, normal also has fifty waves. the node on the top left however is only for 10 waves

[rain prawn]

im very confused how does this relate to doing master difficulty on onslaught?

[dapper steppe]

there is no master onslaught, its just legend onslaught

[rain prawn]

ohhhh I read my quest wrong its not onslaught its an encounter

[dapper steppe]

dm me the image of the quest
