Get Follower to Defend Player

[Kermon]

I'm trying to get a follower of the player to agro onto monsters when the player gets hurt, similar to how abigail does, but I can't seem to narrow it down and I'm still fairly new.

I'm attempting to create a mechanic where a follower character engages monsters when the player takes damage, similar to how Abigail behaves. However, I'm struggling to pinpoint the exact steps needed. I'm still relatively new to this, so any guidance would be incredibly helpful.
