The table below lists what you will receive for each level up. You may click the table headers to sort the table by whichever column you desire. From level 33 and up, items received will always be of the uncommon rarity. Items of greater rarity than uncommon cannot be gained as level-up rewards.
The sequences start repeating again at levels 62 and 91. To figure out what you'll get from level 92 onwards, subtract 29 from the desired level and look the result up on the table. For example, to figure out what you'll get at level 95, look up level 66 on the table.
