Well before the Hearth & home update the raid events after killing Eikthyr boss (which is very first boss in the game) when if i remember right enemies in first event raids where boars and necks and it where not that hard to beat with leather armor, wood shield and flint axe.

But now after the Hearth & Home update the raid events after killing Eikthyr boss became impossible to beat when now the raid event spawns greydwarfs, greydwarf brutes and greydwarf shaman around 15-20 in total that attacks all together like 5 seconds after i get the "The forest is moving..." raid event message and i always ended up dying 2 times in the raid event which cause the raid event to end.

I don't have copper or better gear yet when i have been focusing on building the starting base and preparing to move to black forest to get copper ore and some other stuff in black forest.

Also note that i did create new character and new world after the Hearth & home update, so the "The forest is moving..." raid event is not caused by my very first world i created when i started to play Valheim 7 months ago.

So in short i don't have any chance to beat raid events after killing the Eikthyr boss when without copper or better gear i'm unable to kill greydwarf shamans and greydwarf brutes.
