Bloodborne is one tough game.
However, you can make things easier on yourself despite the fact that there's no visible difficulty level.
As discussed at Reddit , your Insight level dictates the difficulty of the foes you face. It seems that once you pass 15, enemies become much more forbidding; keeping Insight below 15 will make your adventure that much easier. Said one Reddit user:
"With 14 and 27 insight there was a noticeable difference in the two monsters i tested in Cathedral Ward.
Lantern guy gained eyeballs on his lantern and he now casts a ranged Spell. Sycthe guy gains an enchantment on his Scythe that burns you."
Don't consider it cheating. Just consider it a boon if you're ready to tear your hair out. No word yet on whether or not the tougher versions of these monsters drop more Blood Echoes or better items, or something…maybe try it out for yourself.
