+
+Arrows / level:
+Wooded
+Steel
+Gold
+Diamond
+Dig: digs the block it hits.
+Fire: spawning fire on the block or object it hits
+Build: placing a block from the right stack of the bow.
+Toxic: keep hurting after it hits.
+Tetanus: makes you cant move (will not work with other arrows)

+
+
+The target gives a mesecon signal when an arrow hits it.
+
