When you get the item Archangel's Staff from the anvil but your item slots are full,it will waiting until one blank slot. At this time,if you quickly sell an item and buy Archangel's Staff. The one from the anvil wont get in the slot.When there is one slot blank again,you can get the one from the anvil,thus you got two Archangel's Staff at the same time. It also work for Manamune(if you get the ADAPt).
The conversion between AP and Mana will make the AP very high.

After the removal of the arena mode,Chinese players found that this mode is still available in China Test Server(like PBE but only for Chinese player).They rushed into it,leading to the instability of this server.

They even specially fixed a bug that crashed the game

and Tencent now decided to upgrade the test server for better experience.

Official Announcement from Tencent Server

1. part of five people to meet the starting requirement of the game.
2. Trick the enemy into wasting 800 gold by buying anti-healing as their first item, causing them to lack 800 gold worth of equipment during the laning phase.
3. Counter the viego —after defeating Sona, he transforms into a useless three-color fruit platter and gets surrounded and killed by Sona's teammates.

Doesn’t anyone think this kind of champion is terrifying? Constantly emitting a faint green glow in the team, yet no teammates are being healed. Repeating the combo three or four times, all mana is depleted, the enemy’s HP barely drops, and allies get no healing.
