Small changes to original build. but did not seems to have huge difference. choose directly him or this. Youtube link in end.
AM what should have DEF at minimum.
this build have 327k.
you can play around by adding more DEF modules ect.
build should have DEF/Duration/range/cooldown modules and shot focus.
reactor can have Cooldown - Duration up/range if you have it instead.
how to play:
start by using skills in order
1st,2nd,3rd then when times is 2s you should be closest position to wally then use 4th, 1st,2nd and 3rd and hit Wally with a skill.
then aim right legs weakpoint and start shooting on that leg. try aim same weakpoint all time. slightly above center.
and blot twist, if there is a second ajax, void leagake is bugged and first ajax who hit wally with skill gets all dmg.
if second ajax hit first so that ajax player gets your dmg too. not well know bug.
