Next week sometime Heroic Characters - characters which players may purchase pre-leveled to join in current content - will be updated to reflect game changes since they were introduced.
Purchased Level 90 Heroic Characters will come with Level 90 (Adventure only), 320AAs, a full set of gear, food/drink, ammo, potions (as appropriate) and a mount with stats! New Heroic Characters will also start in Eidolon Jungle with content in our Chains of Eternity expansion.
Level 90 Trial characters will come with Level 90, 280AAs, gear, food/drink, ammo, potions (as appropriate) and a mount and be restricted to leveling up to level 91 (Adventure) with restrictions on trading, etc. These characters will also start in Eidolon Jungle.
All players who purchased a level 85 Heroic Character that is still less than 90 or less than 320AA will receive a no-trade level 90 Heroic Character bauble they can choose to use. The new upgraded Heroic Character upgrade baubles are level 90 and 320 AAs.
Players who have a Heroic Character Bauble in inventory will find it automatically upgraded. For more information on accomodations for trial and capped Heroic Characters, see this thread on the Official Forums.
