Hey! I’d recommend joining the Valheim speedrunning Discord, there’s a ton of helpful resources and a great community of supportive Vikings. You’ll find the link right next to the Valheim game logo at the top of this page. Hope to see you there!
New Game Plus is such a fun mode, and a fast one, too! As a solo player, my biggest challenge was deciding what to pack in my starting inventory. In multiplayer, this should be easier since you can share essentials like workbenches and Feasts. I really wished I could bring more portal materials and meads! I experimented with the Karve and Drakkar as my main mode of transportation but ultimately settled on the Longship and the Drakkar only for the Ashlands entry. I also tried building a level 4 Black Forge straight from my starting inventory to be able to repair stuff, but in the end, bringing a few extra sets of weapons worked out better for me.
In multiplayer, split up as much as possible to uncover more of the map and increase the chances of finding Vegvisirs or Boss altars. Only meet to skip the night once you're in higher-level biomes and to share Boss Powers among the team. Eikthyr + Fader + Lightfoot Mead + Ratatosk will make you feel like you're flying for five minutes! When in doubt, head south, it'll save you travel time when going to the Ashlands.
The biggest time sinks for me were Mistlands dungeons and Charred Fortresses and occasionally finding Vegvisirs for Yagluth and Moder. Practice how to efficiently search Mistlands dungeons. For Charred Fortresses, master getting on top of the central tower quickly. You can see the Fader Vegvisir from there if it is there, so only jump in if you see one inside! For Yagluth's and Moder's Vegvisir, it boils down to a bit of luck, unfortunately.
Resist the urge to fight everything in sight, only kill enemies that are a threat or drop something you actually need.
HAHAHAHAHA I feel incredibly stupid, I completely blanked on the fact that the Fader Power gives you extra carry capacity! You must have heard my facepalm from across the pond!
Nice one! The earliest I could get him to spawn in on this seed was 15.550s, but I never managed to kill him on the first frame he appears.
