/set easy 1 for easy mode on and 0 for off. At first climb it is auto on but can be switched off. Later it is auto off but can be switched on.
Horde can only spawn on easy mode off (0)

tyvm, started to be a pain when 3 evil mobs encounter and they heal and can't kill em ...

also if you get lvl 71 easy mode turns itself off so for samurai mq and higher or going for 101 youll have to do 3 mosnters etc

after I got 71 on first char, it changed to 3 mobs and I haven't done quest tho, went until 75 then did it

yeah it only works for 1-70 then after 71 u have to play w/out ez mode
