Just wanted to share that I created a Vital Infusion by putting Mystic Coins, Eldritch Scroll, Ancient Bones and Karka Shells in the Mystic Forge. Apologies if this is already known, but I couldn’t find this information on the wiki and experimenting with recipes requiring Eldritch Scrolls is not done lightly.
There are 6-9 other similar recipes that I guess create other infusions.
The vital infusion gives +5 Vitality +5 Agony Resistance.
Hope this is useful to someone!
