  • You start at the center of the land.
  • You start on one of five different islands on the map. Find portals leading to the other island to explore and expand.

  • Explore other islands via portals and clear the map.
  • Take care of longer winter periods.
Muspelheim (Fire)

  • Attacking waves unfortunately don't provide iron or stone
Idavoll (Heat)

  • This realm is the homeworld of the Ljósálfar.
  • Restrict production Buildings to Oasis zones, build houses / military camps in non-oasis zones

@Wardinary different blade upgrades do stack and both effects are applied. As written in the table it is very powerful to stack e.g. storm blade (for AOE effect) with another (like frost or lightning), then applying these effects not only to the attacked enemy, but in an area around it. Very powerful.
Wardinary 26 Oct @ 1:04pm 
Question: Do powers like blades or tower upgrades stack or do you overwrite one when you pick a different one?
v0vkzk 8 Oct @ 12:53am 
tbh i got really lucky last map when they are going by only one road
v0vkzk 8 Oct @ 12:51am 
thank you, helped me.
Finished in hard mode by lynx solo ( at 8th or 9th year)
3rd last boss stage is pain, especially if its lagging

IMPORTANT: i got heavy lags after 3rd/4th year in peer-to-peer , but 0 lags in Europe's server

@??? Yes the bonus persist. I added a hint:

Befriending them unlocks a new building, which needs to be built to recruit the unit. You will not automatically get a unit for befriending as in classic game mode. This bonus presists among realms, hence in following realms the building is already unlocked and can be built.

Do bonuses from befriending persist?

Thanks for creating this guide, it's been a big help.

@Rogulair this is not a comprehensive Bifröst guide, but a guide on Bifröst Bonuses.
I mainly played Bifröst in Solo Mode and focused on the bonuses. Hence also no building selection or yearly bonuses are added here, which are shared among clans when playing multiplayer mode. There are nice guides and videos out there on this topic.
Rogulair 9 Feb @ 11:55pm 
No clans shared start-with ?

You're welcome! I will return and add more that I discover over time myself, though this time all my new ones you already have updated :)
