Tree Sentinel
"Tree Sentinels are Field Bosses in Elden Ring. These heavily armored knights ride large steeds and carry powerful halberds. Although players are likely to encounter one in their first steps out into the Lands Between, it's wise to leave it be at first and return stronger and more experienced. Tree Sentinels are optional bosses, as players don't need to defeat them in order to advance in Elden Ring. See Draconic Tree Sentinel for a related but different type of enemy"

They say you should never get behind a horse. I guess this would be an exception.
