One Ring is 1d12 + d6. TN is based on the characters attribute score. It creates a system where a lot of actions are only possible on critical success for anyone who doesn't specialize in the skill. 11 is crit fail, so your non-crit maximum is 10+skill*6. Even with one skill level in something associated with an attribute you are weak in, you may have a max of 16 and a TN of 18, making it impossible unless the DM adds a modifier.

Each 6 on a roll lets the player add a little subtle magic to the result though, which is a cool way to implement magic being everpresent and a result of getting really good at ordinary things.
