ELDEN RING

This boss can be found in the Caria Manor, far in the northernmost point of the Liurnia of the Lakes region. Be careful when approaching this manor as you’ll come under attack from magic spells as you approach it.

This boss comes mounted on a horse and loves to use magic spells against you, including flying daggers and a massive bow and arrow that fires an exploding arrow. Thankfully it’s not very fast, almost a cakewalk compared to Margit.

Be patient when learning the attack patterns as the giant spear/club weapon isn’t just for show and will flatten you quickly if you get too greedy.

It's very easy to cheese this boss where she won't even attack you:

Location:

In this video guide I will show you how to defeat Royal Knight Loretta. If you keep following the Northwestern path up all the way North around the lake is where you will find the manor.

How strong to be:

If you have beat Godrick and have at least put a few more points into your character you should be fine if you can avoid her attacks.

Enemy attacks to be aware of:

She mostly uses spectral sword attacks that follow you if you are at a ranged distance. So try to keep a medium range and dodge basic swings and get in for an attack. She also has this nasty charged glaive attack with two sings. Once you see her wind up, run away.

What moves or abilities to use:

Always use a bell summoning of your choice. I use ones with more AI to distract the boss. Plus mix in your preferred ability with your preferred weapon. You could also use a ranged class and use a lot of spells here to avoid high damage. The achievement will pop once the rewards screen comes up.

Here's my video, I'll show you where to go to get through part of this area and the boss fight.
