|
|
|
👋 Hi! I'm a robotic poro who can search for Legends of Runeterra cards to send them in chats!
|
|
|
|
|
|
|
|
To use my features, enter <b>my username</b> in any chat, followed by <b>your search query</b>, like this:
|
|
|
|
<pre>@patchedporobot braum</pre>
|
|
|
|
|
|
|
|
After a while, you'll see the list of cards I found, and you'll be able to tap one of them to send it!
|
|
|
|
|
|
|
|
You can also perform more <b>complex queries</b>, such as this one:
|
|
|
|
<pre>@patchedporobot cost:4 AND attack:7 AND health:7</pre>
|
|
|
|
|
|
|
|
To read all details on the queries you can ask me to perform, visit the <a href="https://docs.rs/crate/patched_porobot/latest">documentation</a>!
|
|
|
|
|
|
|
|
Have a fun time searching!
