Strategy 1) First, make sure you always have your golem up and with Battle Orders so he can take a few extra shots. Then, if you see the Amazon approaching and shooting a few arrows, you cast Bone Wall. Several walls, about 6 will do it, and just keep recasting. Amazons will be confused wondering how you can take so many arrows (being you�re not on their map), and will approach. By now, you start shooting a few Bone Spirits in their direction. Normally, they stop, confused. The moment they stop attacking, you can either bolt (by teleporting) at them, or behind them and cast about two bone prisons on them. By doing this, some of there arrows hit the bone prison, and they can�t run out of the cage. Spamming Bone Spirits will dispose of them.
Strategy 2) Simply charge onto their map and behind them, cast bone prison, and spam bone spirits at them. This is the bold way, but you should be able to tell what Amazons suck and what don�t simply by looking at their showing gear.
ehm... Guided missiles go through bone wallss..
