I am using the UA Revised Ranger in one of our D&D games. I am currently 2nd level and have had my Ranger animal companion from the start instead of summoning him at 3rd level (the wolf doesn't gain the conclave features until 3rd level, as ruled by my DM). He is a normal wolf.
I am training him to use a shortsword during down time. I am going for the concept of Sif the Great Grey Wolf from Dark Souls, who holds the sword in his mouth, but with a much smaller sword.
I am also getting him armor through barding. I have talked to my DM about my ideas, but he never told me how long it would take. By only training during down time, how long would it take for my wolf to become proficient with the shortsword without interfering with adventures? This is not for use in Adventurers League.
