Mount fear is from staying near mobs and also from getting hit (the amount of damage taken determines how much fear is generated so if you get hit for like half your health, its an instant dismount, that includes environmental damage such as getting smacked by a meteor during helltides)
Great information! Just what I needed.
so how much fear does the mount feel when every pebble or corner makes you come to a full stop.
You really wrote all that.
