Bow and arrow are a basic part of many medieval and fantasy settings.
Be it for assassins (silent), for (elven) tribes that live in harmony with nature (not industrialized), or to emphasize the skill of the shooter...
All the more it's important to know how those weapons can be applied and what they are capable of to adjust the weapon use and the equipment the characters of your world have to carry.
Accidentaly I came across a fact I would have never considered:
The flight path of an arrow can be manipulated to a curve to shoot around obstacles (without magic).
This video shows practically, shooting an arrow not from the middle of the bowstring, but from above or below (while the arrow still lies against the middle of the bow) will result in the arrow leaving its linear flight path to perform a curved bulge (around an object if there is any placed at that point) and afterwards return to the straight flight path.
However the distance/range for that seems to be limited.
This video goes more into detail, explaining and incorporating historic archery instruction.
[For example that tricks like an 180° turn, shown here at 0:39, require special blunt arrows without spearhead, with special holes in the shaft and prepared with lead at some points are needed as well as facing the wind in a particular direction which renders that stunt useless for battle.]

I hope this proves helpful to all the medieval assassins and elven warriors who now can show off how superior their archery skills are compared to the steampunk pistols of man or dwarves.
