Many years ago horse skills only showed up when you leveled up. Now in 2022 your horse skills show up grey?
So my question is my horse is lv 30 and it's still got a lot of horse skills greyed out? Why? does that mean the horse can get every skill whats greyed out? and how do you get the S skills on the horse and how can you level them up.
... my horse is lv 30 and it's still got a lot of horse skills greyed out? Why? ...
Greyed out skills are skills, which are available for your horse but are not learned.
... does that mean the horse can get every skill whats greyed out? ...
A horse can only learn skills on a levelup and only until it's level 30.
After reaching level 30, skills can only be exchanged with a horse skill change coupon. (This process is RNG and you may not get the skill you want on first try).
... and how do you get the S skills on the horse and how can you level them up.
S Skills are only available for T8 horses (and up), so if you don't have a T8 you can't get them.
If it's a T8, they are learned the same way as any other skill.
