Does the game difficulty matter in terms of experience points to level up and loot drops?
I am also on death march and it is perfect for me. I also had problems at that first fight same as you but glad i stuck with it. Every encounter feels dangerous but not insurmountable, its just perfect, pretty much like the rest of the game so far. I just finished the second boss (wont spoil anything don't worry) and it was easier than the griffin but that's probably down to the fact that i am now very used to the fighting style. I would stick with death march if I were you it will also make the game last longer, this game is so good i almost don't want to play it because it means that i will be that much closer to finishing it and i never want it to end!
All depends on what skilled gamer you are, some people will find death march easy and some people won't be able to do it at all. Try it, you can always lower the difficulty if it becomes too frustrating. I will say though the very first fight can be very tough if you can make it through that(quen sign is your friend) then it does get slightly easier as you start leveling up and applying abilities to your build. Keep your guard up at all times, keep moving(using the dodge button) and make deliberate slashes with your sword(no button smashing). Also helps to keep geralt at the edge of the fight rather than being surrounded by enemies, if you are surrounded use the roll to escape to the edge as quickly as possible and maybe back off even further to give yourself some breathing room and to allow your spell to regenerate. After that fight try to save before every enemy encounter and apply oils and drink potions for the relevant enemy types, if you have them. Always check the beastiary its very important to know each enemies weaknesses. Patience is key, fights will take longer on death march, trying to spam the same attack to get the fight over quicker will most probably be the end of you. I usually attack humans with a strong attack first then follow up with one or two quick attacks, But for most standard montsers (drowners, ghouls etc) I use quick attack first as they(opponents) are quicker than the human enemies. Hope this helps and good luck!Anyone here playing on DM? If so, do you have any tips and how hard is it?
