Decided to do a pretty much bow only run in Valheim and noticed while fighting the Elder that the little root things he spawns will level up your bow skill. As long as you stay at range from the boss and near a pillar, you can pretty much ignore his attacks while having ample root targets to kill every time he summons them, repeatable until you decide to kill the boss, run out of arrows/durability etc, and they are static so won't dodge you.

It's not AFK friendly as you do still have to avoid the Elder, but it doesn't require you to be in the swamps or find a spawner and build a big setup.

I see this as a sort of fun alternative to some of the spawner/bonemass setups that people have posted as this can be done fairly early, is pretty easily repeatable with seed drops from greydwarf brutes and requires nothing other then to find the boss altar.

Bonus is the boss will knock down a lot of trees during the fight with his range attacks, so lots of wood to rebuild arrows after, can plant more etc.
