Dark Souls has utter bullshittery too. Take for example Curse - instant death, respawn with 1/2 life. It lasts forever (and can stack) unless you manage to reach a random dude some distance from the closest spawn point - with half of your HP.
There is also an item that removes curse, which drops off ONE type of bad guy or can be bought off another NPC. The game does not tell you this, but you will very likely meet this NPC way before you get cursed. So if you look through his shop and read all the tooltips, you'd know how to remove curse as well.
The game does not explain this, and to some that is BS, but I really liked figuring it out.
