anon starting a 5 sovereign run in 3 here.
narmer is way easier than i anticipated. the battle is a slog, 20+ turns because the front row got blinded a lot and the blind just never goes away, but it's very safe. the only danger is when 1 guy gets hit multiple times by the random attack on phase 2.
took 2 tries, first loss was due to bad luck and not bringing nectars.
and so far, 5 sov run is probably the easiest early game i have ever experienced in etriam.
