Hi, I did a quick forum search and found nothing like this so if it's already been posted I apologize. (How many threads have been started off like that)
Alright, this achievement is a little tricky but I found a way to make it much much easier to complete. It's a lot like other bombing runs where if you spam click the bomb item you'll get several shots with it. For this quest it's pretty much the same.
When flying around when you click on the Skyguard Bomb than click on the area you want to shoot you'll get a small casting bar, if you click on the Bomb again before the bar is done casting you'll get another casting circle under your mouse. With this you are able to throw another bomb without waiting for the cool down to finish which allows you to throw two bombs in about the same time as one. After you throw the second one though you'll have to wait for the item to cool down before you can throw your 3rd/4th. This allows you to complete the run much faster.
So again:
- Click Bomb
- Click area to bomb
- Click Bomb again before casting bar is done
- Bomb a second area without waiting for on a cooldown
- Profit
Thanks for reading!
