I saved the hardest for last so here it is:
Quiver of the Forest
Use Unique Power Self Unlimited Uses per day
Only Usable by Arcane Archer
Unique Power will call up a conversation that will let the user decide what type of arrows he/she wishes to summon. The Quiver will then check the lvl of the character to determine the on hit power and summon X number of stacks of Arrows. The Item could be a quest item given to you by Ziggy or the Dryad in d9 or involving both. There could be a limit set to the number of stacks summoned like say a character can have no more than 20 stacks in his/her inventory at one time. Just a suggestion to make Arrows at higher lvl more available since right now the best arrows you can buy are only +10 and do not do much damage for higher dungeons.
Those are my current suggestions, I may think up more later on.
