I then put my 4 attribute points into strength, maximise power draw, put 1 into weapons master and the rest into iron skin. In the Floris mod I go for hunter -> steppe child -> mercenary -> personal revenge. My objective in character creation is to maximise strength and power draw. For these reasons you will need to rely on your companion's skills a lot more than you do with other builds. These require you to have high strength and agility. Not only do you need high power draw but you'll need high riding and horse archery plus you will want some ironskin and power strike.
However, I'll share my experiences of horse archer builds with you in the hope that they help.Ī horse archer is a very skill points intensive build. As the commenters have pointed out there is really no right answer to this! It will be very dependant on what you want to do with your character.
