Having one of your endings tied to a mandatory platforming section while having a talisman that claims to negate fall damage(and doesn't) is a real dick move.
Not only that but the floor falls out beneath you in the end and you then fall further than you did while trying to jump down that hole to begin with and yet somehow didn't die and break your knees.
That being said this is the most Kings Field that Dark Souls has ever been. People were right to bitch about the quest design though, NPCs like Gold Mask don't show up and you can easily miss them. Meanwhile Dung Eater hangs around the Round Table and he's the one where you really don't want to complete his quest.
Honestly though fall damage really shouldn't matter if you're already dead, even Xenoblade got rid of it for this very reason.
That fucking section drove me insane on both of my playthroughs, honestly fuck it. One time I made it to the bottom only to be killed by one of the merchants while trying to get him to break the tentsto get the item.
also let me tell you this, the cat ring is pointless in this game: falling up to 15 ft means you won't take damage, falling between 15 and 20 ft means you take damage, anything beyond 20 is an instant death, the ring makes it so you don't take damage when your fall is longer than 15ft but it won't save you from instant death (the description says this)
I treated it as a stealth mission, used sleep arrows on the archers (from places the assassin couldn't reach me) or outright killed them with incantations/arrows. Didn't bother killing the assassin and THANK GOD IT WON'T CLIMB LADDERS.
Honestly, the consecrated snowfield is one of my least explored areas due to the enemies having bloated pools and dealing a ton of damage. I was looking around the town outskirts for an invasion and died so many times to the archers before I gave up and just rode past them:
Ok they can deal a lot of damage, fair
They have wolves who will stagger you if you try to engage in melee
and there are like three other of them who will spot you right away
AND have a lot of hp so killing them takes a while.
If they ever do a SOTFS type of update to the game I hope they rebalance enemies in late game areas, there's so much I missed there and in mountaintops simply because I didn't want to deal with enemies who take forever to kill and delete my hp bar in a few hits.
