To start, the possibility to trade heroes with other players is a pipe-dream and more than likely will never happen. Setting that aside we all have that 1 hero or group of heroes were chasing after, and we chase them like that magic dragon. If it were possible you could trade for heroes
A. Who would you trade for?
B. Who are you willing to give up for them?
They need to be somewhat equal for exchange I.E. a 4 star for a 4 star, 5 star for 5 star, or group for heroes for 1. (we all want an Alberich for an Alfe, Kuchen for Layla)
They will be traded at the level the are summoned at (Level 1, ascension 1) with no ascension items given.
The hero I’m chasing like most is Gravemaker, I’ve never had the chance to pull him and need a solid fire attacker. I would be willing to give up a few of my extra 5 star heroes, Kunchen, Onatel, Zocc, Seshat or Clarissa. I think giving them a package of 2 or 3of these for him would be more than a fair trade for him since he is considered one of if not the best hero.
I really wish someone at SG could see this! It seems like many people are chasing that dragon and a hero trading market would be something many of us want. Thank you all for showing me I’m not the only one out there. I can only hope that they take a good look at forums like this one and reconsider giving us the ability to trade. Since doing so could be in incentive for the veteran players to bring in their friends by giving them some of their copies.
