 Pestis Infinitum. Roll on the curse table again, ignoring all other results besides this one.

Curse of cracking hands; when ever you pick up an item you roll a d20 if the number is 15 or lower it breaks. (this excludes your own items) if you want to break something on purpose you roll a high or low on a d6(low breaks things)

the folowing have made it in to the cursed table so far there numbers have been written

3 curse of sticky fingers

25 curse of cracking hands

37 curse of deadly words

i will not accept curses that are too hard on the players and as i said the curses have to be bad and good in a way

curse of magnetic luck:whenever you roll a 20 on a  ability check, attack roll or saving throw you must choose a creature other then you within 30ft of you to gain advantage on their next ability check, attack roll or saving throw. however, if you roll a 1 on a ability check, attack roll or saving throw you gain disadvantage on all ability check, attack roll or saving throw  you make before the end of your next turn.
