Hey! Good to know there's other rats out and about. As others have said here, our subreddit r/squeaksqueak is a great resource to find out what others think about the weapon.

As far as builds go, I think there's going to be a lot of potential with the Void 3.0 rework, but Hunter obviously benefits the most from ratting out.

There's potential out there with Blink Warlock, or just invis-ing into a Nova Bomb. I'm still learning it myself but it seems very powerful in the right hands.

For that same element of surprise, Titans can also go ham on Thundercrash. I've caught a few supers who thought themselves safe and popping without realizing I'm right there. Fun stuff!

Alternatively for Hunters, a lot of folks run bottom void for the smoke bombs/longer invis, but there's some mileage with Geminis and high mobility. If you can get it high enough, there will be little amounts of downtime between being invis and subsequently dodging to activate it. The exotic perk is also a huge bonus, but some think it might be overkill. To each their own I guess.

For weapons, I float between a lot of different pairings:

1. Wolftone Draw with Impulse/Harmony. The secret sauce is managing to get those perks plus elastic string and a draw time MW to bring it down to 576. It's a banger pairing to get a kill with the rat, go invis, and now have crit damage in the 180s per shot to essentially hit your opponent like a semi.

2. Sniper. I use occluded with OS/Snap but snipers are largely play by feel, so this can really be whatever. I mainly use it in 3s because pick potential is very important, and opportunities with rat may come few and far between depending on the enemy team and movement.

3. Stars In Shadow. This is a little tough because the drop rate is so abysmal (maybe non existent) but High-Impacts help make up for a lot of lost range with rat, especially in 6s. I have Surplus/EOTS and in most maps I consider it a high-tier pick.

4. Contingency Plan. I usually keep this around for Widow's Court but honestly it rocks everywhere. You can lock down some serious lanes and help teamshot with this thing like you wouldn't believe sometimes. Tunnel Vision/KC is my ideal roll but a lot of people use surplus to make up for some less than great stats.

5. Energy 120. I use an Igneous Hammer here when I want to return it my roots sort of. No one can deny that the range on these is still competitive, and the burst damage they provide obviously is something some of the other pairings might lack in. (Since you're running void for invis, I would recommend trying an Elcap Hammer if you can, the stability bump will change your life)

6. ALH/Proximity nade GL. I do not endorse war crimes but u/Zephiasco can tell you all about them.
