On April 15 2014， an update to the bot AI was released， primarily improving threat evaluation and the ability to dodge skillshots， as well as updating the item builds used.
Bots can be used for:
- Practicing against or learning how to play a new 英雄;
- Filling in for missing players to even out teams;
- Leisurely play for those who do not want to experience such competition between summoners;
- New players who want to familiarize themselves with the game (英雄， maps， 道具， item builds， 英雄 skills， strategies etc.) before competing with other summoners.
符文 and 天賦
Intermediate bots take 15 mastery points and have 16 符文–five each of 層級 2 Marks/黃之紋章s/藍之雕文s and one 層級 2 紫之精髓. Intermediate bots have no increased 屬性 except for a boost to their 被動 gold gain.
Beginner bots have neither 符文 nor 天賦.
Since this update are 54 of 123 (43.9%) 英雄 available as bots.
英雄 with a were available prior to the V188.8.131.52 update.
Prior to V4.7， only 29 英雄 bots were available in custom games， and could only be at beginner difficulty. Custom games now allow all available bots at beginner or intermediate difficulty.
Some bots have been only sighted in 據點攻略戰 mode.
To add a bot into a practice game， you must first be the creator or the host of the game. Then， click the “Add Bot" button on the right of the empty slot to add a bot to the corresponding team. Once a bot has been added， you can then change the 英雄 of the bot by selecting it from the drop-down menu.
- During Sona的 release in patch V184.108.40.206， she was unintentionally added onto the bot roster. Bots’ names are usually made up of the 英雄 name followed by the word “Bot" (e.g. 安妮 Bot). However， Sona went by the name “game_bot_sona". She did nothing but 自動攻擊(普攻) and she was removed from the bot roster with V220.127.116.11. She has been reintroduced as a standard bot with the Rise of the Bot Army update.
- After the update， 納瑟斯 and 亞歷斯塔 appear to be scheduled for removal as bots. However， it is possible that they will still be able to be selected in custom games， but won’t be available in random player vs AI games. They， together with 墨菲特 and 希維爾， were unavailable in that mode before the update.
