League of Legends, where did the silver and gold frames come from?

First, the reward at the end of the season.

Second, S4 season awards are as follows

1. Avatar Branch Settlement Award

From top to bottom, it is from bronze to king. It is worth mentioning that the king's avatar reward is divided into three avatars. From left to right are different single-row avatars, 3V3 and 5V5.

2. Followed by the border of the game login interface, from left to right are silver, gold, platinum, diamond, master and king. It is basically the same as last season, except that the login box of the master group is added.

3. The next step is the border reward outside the game.

4. Reward the skin above the gold level, Morgana, the goddess of victory.
