Luck.

In WonPil, the powers of Avatar of Tifiul manifest this way:
• Infallible aim with weapons ;
• Prediction skills ;
* Using luck to make some accurate choices that always come true. Similarly to Jiho, he can make some little predictions of the future through tarots and other means. It doesn't have anything to do with time, but only in choosing, thanks to luck, the card with the right answer.
He is also extremely successful in gambling.
• He can, mostly unconsciously, grant brief periods of luck to other people, but not to himself ;
• He can create luck bringing items (jewelry and gems) and drinks with special properties.

Note: the Avatar of Tifiul needs alcohol in his diet. They could as well only feed on it without touching other food, but if they only eat food and don't drink alcohol, their body will suffer from malnourishment.
They can't get drunk from alcohol.

* Thanks to his passive powers from Fiared, he is surrounded by a magical shield that protects him from getting seriously injured. That's what kept him alive even in the most dangerous situations.
The downside of the shield is that it absorbs magic used against him and leave him with issues like the cold he always feels.

Seelie powers:
• Better reflexes (when he is focused) ;
• Superior agility (when he is focused) ;
• Enhanced senses, especially hearing and eyesight ;
• Ability to manipulate dreams of other people.
