I love this mod and your RPG Series, and with the recent addition of Quivers I'd like to suggest following Features:

New Arrow Type Ideas

Broadhead Arrow
Iron Ingot in place of Flint
Deals more damage, but slower pull time

Ricochet Arrow
Slime Ball in place of Flint
Bounces off Blocks

Balanced Arrow
Amethyst Shard in place of Flint
No Randomness to flight path

Echo Arrow
Echo Shard in place of Flint
Homes onto targets

Tracer Arrow
Torchflower in place of Flint
Provides Light mid flight, increasing in strength when landed

Bomb Arrow
Gunpowder in place of Flint
Non Destructive Explosion on Impact

Rocket Arrow
Non Exploding Firework in place of Flint
Faster shot with less projectile drop

Named Arrows stuck in blocks display a nametag

Quiver Arrow Selection
Ability to Ctrl-Scroll to change selected Arrow inside the Quiver, and an "Offhand" Style slot on the opposite side of of the Hotbar displaying the current arrow type and amount.

Specialized or tiered arrows are a asymmetric feature, as Wizards have no rune tiers, nor do melee classes have anything tiered consumable.

This also brings another factor for balance calculations, making things even more complex.

I strongly oppose the concept.

Thank you for taking time to review my idea
I can see how this could pose a problem, especially in constrast with the other classes
