I just took a look at Chaos Bolt and see that I can free transfer to Crusader Strike and Wild Growth fine.
Make sure to:
- At the character realm list, select the Shop icon bottom left.
- Then select “Free Character Transfer” this is the first button on your left.
- Fill out all details or tick the options. (See image)
- Click on Continue. Your character will now be prepared to transfer and is irreversible. Since the realm is closing anyway this is not really of any consequence.
Another player here said he couldn’t transfer too, when it was opened for other realms and we came to the conclusion he was attempting to use his paid transfer token which you can’t use on the Seasonal realms.
