Caddy, you are correct that it takes 170 wands in total. If you factor in the bronze, silver and gold doors, you need 170 wands in total.

But I believe the original question asked how many wands to break through 5 golden doors (not factoring in the bronze and silver doors), which would be 500. At least that's how I read the question? :/
