Arrow Recovery gives you 33% chance to recovery a special arrow after shooting it.
Arrow Recovery is a talent in Divinity Orignal Sin 2.
While there aren't that many great talents to begin with, I skipped this on my Ranger during my Honour mode game. Elemental arrows were more plentiful than I could ever use (started selling them) as physical damage was more important in most cases, and Charming Arrows are the easiest to craft (by the beginning of Reaper's Coast, you have access to a bee hive and can find around a dozen honey jars that you can infinitely replenish, and arrowheads are dirt cheap, let alone arrow shafts). The only other arrow that would be useful to have more of would be Knockdown arrows, but most of the time, my Ranger simply kills the enemy with massive crits rather than needing the knock them down. Honestly seems like a waste of a talent to me.
not a must have for a ranger but if you find yourself using the special arrows like charm or knockdown or even the elemental arrows it can be quite amazing.
