the pot would cost from 32 to 64 depending on duration of the pot, it would allow people to go past bridges without being seen and would make the game more exciting and more tense. It would also prevent people from camping for so long and overall make the game more tense and better, Also invis pot would bring more strategy to the game. If people like having invis pot in game we could also introduce custom pots in the game for example in Op mode we could have strength 3 for 64 diamonds, or blindness 5 etc to throw at enemies.
