The Radstag is part of Appalachia's fauna and one of Fallout 76's simultaneously majestic and disturbing mutated animals. These post-apocalyptic deer also drop meat, hides and blood that can be useful for both quests and crafting.
If you're in a hurry to find Radstags in Fallout 76, you'll have better chances of doing so at a handful of specific locations. One of them is the farmhouse east of Dent & Sons Construction in the Savage Divide, where you'll usually find no less than four Radstags.
There are other locations where Radstags are likely to spawn, as well. You can find trios of them spawning on Twin Lakes' northernmost lake and near the strange tree with hedges southeast of Marigold Pavilion.
They can also be found on a dry lakebed between Lakeside Cabins and Summersville, in the junkyard west of Hemlock Holes and on a farm field south of Gilman lumber mill.
You can also spot Radstag corpses south of the Overseer's camp and in Flatwoods, near some tents.
Fallout 76 is currently available on PC, Xbox One and PS4.
