The Stop-Watch is a rare item that can be found in the Dungeon or bought from the Steampunker for 3 Platinum coins. Upon using the item, everything (except for bosses) will freeze for 10 seconds, allowing you to either easily kill them or run away. The color scheme is similar to that of The World from Jojo's Bizarre Adventure, as is the effect that plays when the Stop-Watch is used. It can be sold for 23 Gold coins. Going back to the 'everything will freeze' point mentioned earlier, time itself will stop and enable the 'Stop Time' buff. Tooltip: You thought it was a tooltip, but it was me, Skeletron!
I haven't made anything like this for a while, so sorry if it sucks.
