Try this challenge.
I believe I recall dying on an alt sometime on a beta weekend. I was completely broke when it happened. The WP was actually free when I needed it to revive from if I remember correctly.
Atleast the money in your bank will be used when you need to WP and your character is broke. Not sure what happens after, if what LinkR describes is still the case.
I thought that if you don’t have enough money, the WP costs are directly deducted from your bank?
If you have absoltely no gold the nearest wp ress will be free
No gold on character = withdraw from bank.
No gold on account = free.
