Your blows land on your own faction again, grudges hold in multiplayer, and form attacks and powers train the skill they scale with. None of it was tested in game, so please report what you find.
Each Skeleton player can choose to eat and to spend stamina, the Aswid can't take wing in the middle of a fight, the Dvergar build the black marble set with stone, and a faction can fight as a group. None of it was tested in game, so please report what you find.
The old bat flight is back as a choice, the Fenrir forms sense nearby creatures, and the Grafvaettir's drones finally dig copper and tin. The drones were tested in game; the bat flight and the senses were not, so please report what you find.
The vampire was all strength and no price. Infinite stamina, a bat that crossed the map at 50 m/s for free while its aura drained everything below, and no real weakness. Players on Discord said so, and they were right. v1.6.1 gives the Aswid a cost for its power, and makes each part of that cost configurable.
A one-fix release. With the Valkyr body replacer, leaving a monster form brought your body back without its hair. Now the hair comes back too.
The Skeleton can laugh, the Furling's fire reaches crossbow bolts, and transformed players stop firing a crossbow they aren't holding.
Valheim 1.0 brought new creatures and new meat, and none of the mod's diets knew about them. Now the Aswid can devour them, the Draugh eats the new raw meat, and the Skeleton can pick its look in the barber's chair.
A player asked for a way to translate the mod. Every text it shows now lives in plain JSON files instead of its code, and it ships in English and Italian. On the way, Valheim 1.0 turned out to be sorting two of the mod's stations into the wrong build menu, the Trol's True Form was switching itself off, and the Aswid's Eclipse had never worked at all.
Players running certain magic mods kept reporting purple smoke around a Skeleton's burning skull. Chasing it turned up something larger than one bad effect: the mod asks the game for things by name, and nine of those names are not in Valheim at all. Each one failed without a word, which is why an item promised since 1.4 had never once dropped and a whole attack had never made a sound.
v1.4.19 taught the Fenrir's forms to walk on other people's screens and said plainly that the attacks would need their own fix. This is it — along with a Fenrir who turned back into a human at every sunrise regardless of what the tier allowed.
