T&B doubts and questions

[D. Brownie]

Hi all!
Yesterday I played my first game of T&B, but I and my Brother had some doubts we solved with gentlemen agreements... But should be Better to know exactly what the right way. And here Is possible! Fantastic

- A Natural roll of 10 Is Always a success with destiny roll, but also in shooting and fighting or if someone can't equal One  opponent armour rating won't be able to hit him without support?

- If a wizard casts 3 # spells and 3 other spells (2 in each phase), can he ipothetically cast 6 spells in a turn?

-with the heal spell, does the wizard have to stay all the turn healing or since Is "instant" you can roll the healed destiny roll immediatly?
