Here's a few of my favorites:
#476 - Drop plate visor at your feat, sometimes opposing DG's will right click on it, instead of you, and save you from being attacked for a moment. Also will fill up one of their inventory slots, causing prescious seconds of confusion when they return to base!
#23 - Sell plate visor for 480! Any item shop will give you this awesome deal!
#804 - Pinch those pennies! If you need to remind yourself to keep an item slot open, you can buy a plate visor and keep it in that slot until the item you really want is in your cost range.
#167 - Plate Visor can be bought and then given to teammates, allowing them to sell it. This lets you pool your resources together nicely!
#200 - Are you one of those people who has a hard time with words? Plate visor's description Text is the shortest of almost any item in the game!
So, which of the 1001 uses for Plate Visor is YOUR favorite? It keeps moisture off of coffee tables, it even prevents (most) rain from getting on your face!
Warning: Do not attempt to use plate visor in game, even with all these great suggestions, as it is bad for your health, and may cause 'feeding' in opponents.
