Offering Altars are a type of Collectible in Assassin’s Creed Valhalla (ACV). This guide shows where to find all Offering Altar Locations in AC Valhalla (11 total). They are needed for the Completionist All the Way trophy or achievement (100% Completion).
Offering Altars count as Mysteries. On the world map they are marked by this icon: 
. You can still access all regions after the story to find them.
Offering Altars require you to pay tribute at an altar. This can be simply some silver coins or it can be other items such as fish or hunting goods. Then you place the item at the altar and it will count as complete and give you a skill point.
For a region by region guide of all Mysteries refer to this guide: Assassin’s Creed Valhalla Mysteries Guide

Ledecestrescire
Offering Altar #1
You will need to offer 3 x Hare’s Foot for this. Luckily, you’re in a clearing full of hares and the altar gives you unlimited arrows. Simply shoot 3 (use Odin’s Sight to show the hares in white) and loot them for the feet.
Grantebridgescire
Offering Altar #2
You’ll need to offer 10 Bullhead (Small) fish for this one. This means either going fishing for them by building the fishing hut at the Settlement and obtaining the rod or by getting wet and jumping in the river yourself to melee/shoot the fish. The river that runs past the Settlement is the best place for Bullhead (Small) as larger sizes won’t count.
East Anglia

Place 200 Silver in the bowl. Thankfully no hunting or fishing required!

The first altar, and any others I went to, only gave skill points. Definitely not unlimited arrows.
I dont recive any fabrics from chests after fully upgrading my rations and arrows, so i cant offer to that altar 🙁
They added more fabric in an update.
Still having the same problem, even after the update
I have tried fishing and I can’t get the brown Trout or the other one 😭😭
On the west coast of Oxenefordscire, there’s a town called Oxeneforda. Zoom into that on your world map as much as possible. To the left of that town to can see a small island where a standing stones world event will be (blue dot on that island) in the region Glowecestrescire. The water around the island there is shallow enough for you to walk in. Equip two spears and chase after the fish while attacking! I got them in literally a minute. Also the fast travel docks in Northwic, East Anglia (kind of in the center on the Wensum River) has the same kind of shallow water but it’s on a much larger scale. This one sadly has very little to no brown trout but it has plenty of other fish! Hope this helps! Good skills to have to make it a little easier -> Heavy Dual Wield on the red skill set and Auto-Loot on the yellow one.
