I haven't done a whole lot with the crests as I found the starter crest to be very versatile and I got used to the moveset. I have played around with the Beast crest which is really fun, allowing you to just go ham on enemies. However I found against bosses the Beast crest doesn't work at all, as the damage taken is too large for the lifesteal to overcome. Unless you are dodging and weaving, which defeats the purpose of the Beast crest a bit.

The patches that have been release will probably help a lot of people with the bosses as, if I understood correctly, they've decreased the contact damage. This will help a lot with the feeling if boss fights being unfair due to hits taken are often compounded by subsequent contact damage. On many occasions I've gone from 4 health, doing OK to dead in less than one sec. This can feel very unfair. Especially after going through a long and annoying run back and then 2 easy phases, just to get to the hard part and die right away.

It feels like if one were to simply be able to practice the hard part, bosses would be defeated much faster. The runbacks (which often include shortcuts it must be said) combined with long easier phases contribute to a feeling of unfair difficulty. It also makes things take up more time than needed, leaving people to feel like the game is wasting their time. Or difficulty for the sake of being difficult. As the video stated, difficulty is a tool that most be wielded carefully.

When doing for example a SL1 run in a Souls game, the player must play at a high level without many or even any mistakes. Boss fights will take longer and the stakes go up. The difference is, one chooses to do these challenges. Often only after already mastering a game. For many people Silksong feels like being thrown into the deep end, without being able to properly swim.
