Wow , this is kinda a where do I start type post . The thing that makes this hard to answer is that his ult is so versatile . There really isn ' t one way to use it . How I usually will use it is to , In lane disable a turret for tower dives or to set up a q stun or other cc with teammates . Or in a team fight I will usually use it to disable a high damage enemy ADC , Assassin mid or jg , etc . can also be chained with q stun out of ult or I will sometimes use it to lock down enemies as they try to run away after the bulk of the fight is over . But keep in mind it is a fairly long cool down and it is sometimes very important when securing dragon or baron . I assume you are fairly new to bard with a question like this , but my main advise is just play him more . you will find a pretty visible learning curve to it where you feel like you just know how to use it , and when . I hope this helped , also apologizing in advance for any grammarspelling mistakes as I typed this in a hurry .
