Elden Ring - Circling to Kill Giants (Low Level Strategy lol)

I'm six months late but I'm finally playing Elden Ring on PS4. I picked a Confessor-class so I could be an incantation-wielding swordswoman.

The main quest of Elden Ring is to collect the broken pieces of the Elden Ring from a goddesses' demonic children and become the Elden Lord.

In this video, I recently died while sheepherding giants into attacking each other. Following my compass display overhead I have to grab the runes dropped at my death so I don't lose them forever.

Not sure what level I am, somewhere in the twenties -- I have a sword, shield, and two spells: healing and fire ball.

I use or goat-horse steed, Torrent, to quickly return to where the five giants are waiting for me.

Thank the Elden gods for Torrent's double jump which saves me from losing help from a steep fall.

I start with two giants and get them to attack each other while aiming at me. It's then that I notice their stagger and try to attack them while they're down but I'm not doing as much damage as they're doing to each other.

Alternating between my health flasks and my healing spell when I dismount, I try to fix my health when I ride too close or get cornered resulting in damage.

The giants do a lot more damage to each other when using their giant swords.

There's some kind of large identation or hollow at their abdomen, perhaps a well-timed fireball will do a decent amount of damage.

Sometimes when the giants fall, their heads emit a gold light ... not sure what that is.

After downing one giant, I ride toward another seated nearby and bring him into my sheepherding circles of death.

I'm not sure if Torrent has a limit-time to riding him or her but I find myself jumping off them and having to remount.

I finish off the 3rd giant with a fireball and do something similar with the other two in the distance.

Hopefully I can figure out how to kill these guys easier but it's nice to get 1000 runes per kill, sometimes without me even attackign them.
