Hello. So, suppose I buy a heroic on the Tribunal server and get the 15,000 plat. The plat is a one-off even if I buy more heroic characters. But what if I buy one on a different server, for example the Zek server? Is there an additional plat reward for a new server?
Plat and other one time only stuff comes with each one you purchase. If you mean can I buy then delete you get none of the items, you do spawn with the spell book full and gear.
Each one you purchase - per account? Per server? Or can you buy 3 heroics on one server and get the plat each time?
Heroic characters can be deleted and reused (for instance, to create a new heroic character of a different race/class). This is when the 1-time limit on the bags of plat and other tradeable items comes into play. You only get 1 bag of plat per Heroic token, no matter how many times you reuse that token.
