Amethyst + Bandit = Perma Speed Boost Exploit

This is a really hilarious (and exploitable) bug/exploit in the latest version of Risk of Rain. Play as the Bandit, pick up an Amethyst. Now, use Smokebomb, Amethyst to reset, and Smokebomb again before the first one wears off. Instead of just reactivating the skill with the normal speed boost on top of your base move speed, the second Smokebomb adds its speed increase to the first, and when it wears off, your speed gets dropped down to what it was when you used the first Smokebomb. Every time you do this you get a permanent speed boost.

This is abusable so easily that with little effort you can reach a ridiculous movespeed in the time it takes to beat a level.
