Rolling 7 or more/0 or less

[Shade]

With d6 we can roll 0 or less(chicken on ur head etc), 7 or more (munchkin dice bag etc). What happens when such values ​​appear, If the events of the card are written within the framework of 1-6. For example, chameleon from supermunchkin (when you encounter a trap for any reason roll a die. On 1-3 you escape. On 4-6 the trap is effective...). Thanks.
