Man, Odr is tough.

[Fargo]

I thought the beating Immortal Redneck with the Plague Medallion was hard but I may have met my match here.

I've seen some threads on here about tweaking Odr. One thing I would do is not drop items that Odr can't actually use. It is frustrating to get healing items that I would love to have as any other character.

Beating Immortal Redneck with the Plague Medallion was small potatoes compared to this. I was able to get to the final boss on Hard with Odr, but got taken out before I could get my final hit in. Kinda gave up after that.

Yeah I got to Nidhogg and got him down to half health and then got taken out. feels bad man. But i'm still trying

Nidhogg has one (1) attack that can end run suddenly. It's aimed shot that you MUST dodge via dash (left/right). Most other attacks are more or less predictable.

as of items that have no use for Odr, you can thank clueless devs for them. Any sane roguelike game does adapt for different characters, if in some details.

Just completed Odr on hard after what had to be close to 100 attempts. Just keep at it, You'll get there!

I had damage and luck maxed out, 7/9 range, almost no precision. I used the revolver up until Helheim II and then got the minigun. For equipment I had the 'one extra life' shield (which I didn't end up needing), the 'Strike to the beat' boots which I switched out for Giant Slayers when I got to Nidhogg, the helmet that does extra damage on perfect rythm and the bracelet that drops more coins. Skeleton key helped too.

I was also concerned about the wave attack that Nidhogg does in his second phase where the only way to avoid it is to dodge THROUGH it, which I never seem to be able to do. That's how I lost one of my runs on the last fight. But if you focus on damage stat upgrades and damage items and get a decent gun, you can melt through Nid pretty quick. I think I only had to reload twice.

TLDR: Practice and good RNG
