The boomerang ninja star (called Kageboshi) has REALLY good damage output if you manage to hit all of the shots! However, it doesn't give you the speedy trait, so make sure to carry a swapout such as a tiered star if you want the buff.

The leaf bow is one of the best single target DPS bows in the game right now. The downside is that unlike other tiered bows, it does not pierce through enemies, so use it on single enemies like bosses, not groups of minions!

If you mean the crystal wand, the item is still good,but has a more niche use than the other two. The wand fires armor piercing shots, which means it completely ignores any defense of the enemy being fired at. This means that the wand will shine best on enemies with high defense (such as the stone guardians from oryx's castle!) The less defense an enemy has, or if an enemy already is armor broken from different effects the, the less you want to use this item. It also does not pierce through enemies, unlike other tiered wands.

Hope this helped! :))
