Heal ball is so insane. If you have Kelvin and you get the levels, he snowballs lane(haha) and you can buy your early items freely. Definitely gonna be picking fast healbane in a K lane.
Trik shares a lot with Kelvin, he leaves everyone cold and dead in his wake while running from a team trying to hunt him down and bring him to justice.
You should look into filling your weapon slots with 500 cost items at least. Free stats. Worst case scenario you can get back 250 if you need it. Usually an additional slot is more important than an upgraded item unless it's core to your build.
It's not outputting dmg while it's swiping or stunned. So if you're hard committing and your prey hugs tower you can buy another shot or abilities worth of time before you start taking dmg again. Very niche, very dangerous.
