Ah this thread again. 100% agree, the mist is terrible and the wisplight completely useless.

I went the modding route, at first DeezMistyBalls[valheim.thunderstore.io] to increase the wisplight radius, then I decided ♥♥♥♥ it and switched to MistBeGone[valheim.thunderstore.io] to remove the mist completely.

Wisp torches are supposed to be changing so that mobs don't attack them, but since they were useless anyway that doesn't matter to me.
