This solution works for those who have completed the main story, or are up to Sequence 9 Memory 1.
Credit to HolyHalfDead for a big chunk of this solution.
It goes without saying, but make sure you have smoke bombs on you.
Progress through the memory up until after your horse is killed, where there is lots of enemy territory to get through. There will be lots of enemies with spears and axes that you can use for long and heavy weapon throws.
First you want to lock onto a guard at the first ruins. This can be the guard who wanders by himself, or one of the two stood at the doorway. Then back away from the guard as much as you can without the lock disengaging. Finally throw the smoke bomb by facing the gard and hitting
.
After this, you want to start a fight with the guards. This will Cause alot of guards to circle you, but just be cautious and get an execution streak going and you will be fine. When you have either killed them all or have caused them to run, you can walk over a spear or large axe and press
to pick it up. Then, like with the smoke bombs, find an enemy and lock on. Back away as much as you can. This time, you want to hold
instead of press it. This will throw the weapon. You need to do this with a spear and an axe.
Hope this saved some time and helped someone, if you have any improvements let me know in the comments
