Now, let's say a 1st level human Cavalier picks a horse for their mount. What do the rules say - does it have to be a light riding horse?
Or can they start with a heavy horse?
Or even an advanced horse?
I've seen several of these variants, but I don't know what's within the rules, and I'd really like to abide by them.
If these other variants are legal, do they also progress through the levels according to this table, so all the bonuses listed here apply to them as well?
Also, can I raise my horse's intelligence to 3 by any means?
Even by raising an ability score once it reaches level 4?
Thanks in advance!
You'll help me a lot!
"A cavalier gains the service of a loyal and trusty steed to carry him into battle. This mount functions as a druid's animal companion, using the cavalier's level as his effective druid level. The creature must be one that he is capable of riding and is suitable as a mount. A Medium cavalier can select a camel or a horse."
It's the Druid animal companion Horse. Check the Druid section of the CRB for the stats.
