Weapon walk[edit source]
Can you use this animation while wearing weapons? E.g. sad walk doesn't show when you have something equiped.
RE:Weapon walk[edit source]
Only when the weapon is sheathed. Same for angry and proud walk too.
Here's a list where the animations play idly when a weapon is equipped; nomad sandstorm, barbarian, spirit hunter, revenant, zombie, hot sand, assassin, plague doctor contagion, the risen. Slomo works but you don't see the weapon equipped. 
Not sure about jester walk, I don't own it.
