サモナーズリフトへようこそ
こんにちは。クラウドエース バックエンドエンジニアリング部 の伊藝です。
みなさんは、League of Legends をプレイされていますか？
League of Legends (LoL) とは、Riot Games が開発した 5 対 5 のマルチプレイヤーオンラインバトルアリーナ (MOBA) ゲームです。
私はほぼ毎日プレイしています。
ゲームをプレイしていると、周りより強くなりたくなりますよね。
LoL は課金で強くなるゲームではなく、プレイヤー自身のスキルと知識が勝敗を分けるゲームです。
LoL では、チャンピオン (キャラクター) ごとにビルド (アイテム構成) があります。
ビルドを間違えてしまうと、強くなるどころか弱くなってしまいます。一般的には、ビルドは統計データやプロプレイヤーの動画を参考にして考えられます。
しかし、有名なビルドは対策方法も広く知られているため、新しいビルドを考えることも重要です。
そこで、今回は LLM (AI) に LoL のビルドを考えてもらいます。
環境
扱うデータ
League of Legends の Data Dragon という API を利用します。Data Dragon は LoL のチャンピオンやアイテムなどのデータを JSON で提供しています。
問題点
Data Dragon から全チャンピオンの詳細データとアイテムのデータを取得すると、合計で 2.5MB のデータになります。
LLM は、入力データが大きすぎるとトークンの制限に引っかかる可能性があります。
大きいデータを扱う際には、データを小さく分割して処理するか、データを圧縮するなどの対策が一般的です。
しかし、今回利用する Gemini 1.5 Pro は 100 万という大量のトークンを扱えるため、データを分割せずとも扱うことができます。
コード
Data Dragon から取得したデータを LLM に渡してビルドを考えてもらいます。
LangChain というフレームワークを使うことで、LLM を簡単にアプリケーションに組み込むことができます。
プロンプトでは「誰も考えたことがない、勝率 60% を超えるようなビルドを考えてください。」と指示しています。

LLM にビルドを考えてもらうことに成功しました。様々なユニークなビルドが提案されました。
ダリウス (Darius) Jungle に関しては、あまり一般的ではありませんが自分のお気に入りのビルドに近いです。
しかし、アイテムの情報が古いものになっている (削除されたアイテムが含まれる) など、不確実な部分もあります。

Kraken Slayer provides on-hit damage, Berserker's Greaves, Runaan's Hurricane, and Phantom Dancer maximize her attack speed, while Infinity Edge and Guardian Angel offer damage and survivability. Lethal Tempo synergizes with her attack speed, Presence of Mind ensures she has the mana to spam abilities, and Legend: Alacrity further boosts her attack speed. Triumph and Legend: Bloodline provide sustain and survivability.",

まとめ
LLM に大きいデータをまとめて与えて、LoL のビルドを考えてもらうことができました。
問題点として、アイテムの情報が古いものになっているなど、不確実な部分もありました。また、ビルドの提案はユニークなものが多かったですが、実際に使うと弱かったです。
LoL で勝ちたい人は、op.gg などの統計サイトで最新のビルドを確認することをおすすめします。
また、ユニークなビルドを試すときには、チームメイトに迷惑をかけないように注意しましょう。
