When a player level ups, corresponding rewards will be given. Some are "Tower Level Up" and some are "Rewards".
■Player LV.４→５ Reward：Tower Level Up
■Player LV.５→６ Reward：Gold +1000
■Player LV.６→７ Reward：Tower Level Up
■Player LV.７→８ Reward：Gold+1000
As such, Player Level and Tower Level are not linked and the level will not be the same.
Details pertaining to level up rewards can be verified under "Regarding Player Level Up Rewards" in our FAQ.
