Sea of Moving Ice is the second part of module 10 “Storm Kings Thunder”. It extends the adventurers’ journey in the cold north, introduces Fishing and boat travel and concludes the story of Svardborg and the Ring of Winter.
First of all you need to follow the quest story line. It might be hard, but if you find a group it can be done. When completing the story line, you will receive a free rusted relic weapon set.
This weapons is useless, but don't discard it right away!
You need to restore these weapons if you're planning to use them. How. see our weapons section.
Next in Sea of Moving ice, you need to grind it.
Also complete the Storm King Thunder campaign. You will need to complete at least the 'scout cold run' (for access pass to cold run area) and 'unlock fang breaker island' (epic skirmish)
There are a few fish that can also be caught in the weekly quest Runestead. So if you are looking to get the complete fish collection you will need to fish the small pond in the north of the map. There is a teeny tiny fishing hotspot here inside a small cave on the pond. Park exactly on it to get the bonus for catching the more rare fish.
There is also a hidden treasure chest on the very northern snow drift. Might as well get that while you are there.
