Achievement Idea Thread

A simple thread in which we can suggest ideas for additional achievements to eventually be added to the game. Here's my ideas:

• Taste of your own Med-eye-cine: Hit the Beholster with the Eye of the Beholster. (Originally I wanted to make the achievement to kill him with it, whether partially or entirely, based on the last run I had where I literally only used that gun because I thought it'd be ironic. Also because shit's OP yo)
• Stop, Drop and Roll: Roll 100 times while under the influence of the Fire debuff.
• Long Live the King: Defeat the Bullet King, but leave his Chancellor alive when you proceed to the next Chamber. Would work
• The Myth of 'Totally Not Copyright Infringement': Use the Grappling Hook on 50 wooden surfaces (Brown chests or wooden walls count, as well as tables and anything that's clearly definable as "wooden").
