The Mist torches are helpful. But they only dissipate mist at ground level, and they become an immediate target for all creatures in the area to destroy. So you spend more time maintaining them. I feel instead of the torches, they should build in stationary indestructible wisp fountains that you can refill. Maybe 1 Wisp gives you 10 mins of coverage. And it would clear the mist in a larger area, ground to sky, for a short period. This way you still need to catch the wisp but not building hundreds of torches that do not last. Mistlands is a scary beautiful biome and I'm enjoying all the new additions. If they mist was modified it would be a great biome.
