Any reason to use slacker pin?

I feel like I'm the only one who bothered to give the Slacker pin a real try. The trick is that the Slacker ability "Tool Around" becomes EXCEPTIONALLY powerful towards the end of the game IF YOU USE IT CONSTANTLY.

As you may have found, Tool Around does absolutely nothing useful when you first try it. However, Tool Around is not as simple as it seems. From my experience and based on best guess, the game counts how many times you have previously used the ability. As the number of times you have used it increases, Tool Around starts doing other things besides just skipping a turn. Once the ability has been used a fair number of times, the equipped character will either: perform a low damage attack, a self-heal, cast a spell on self called "Zen" (no idea what it does), or skip his turn. Which result will occur appears to be random. However, the more you use the ability the lower the likelihood of skipping a turn and the more powerful the alternatives become. By the end of my game, Tool Around was resulting in full-party heals (which was named "Hookah" when cast), as well high-damage single and multiple target attacks (can't remember the names right now).

Admittedly, Tool Around still sometimes results on occasion in the character in question doing nothing even when the ability is "leveled up," but the sheer power of the other high level abilities make up for it. You never know what you're going to get when you cast it once it's leveled up, but more likely than not, it will be awesome.
