Do I need to take each child perk along the perk tree in addition to meeting the skill requirements for perks?
For instance, the smithing perk tree is split into two sections: The left, which features light armor (Elven, Glass) and the right, which features the Heavier armor (Orcish, Ebony).
The Capstone Perk in the tree, Dragon Smithing, has "feed-in" lines from both Glass Smithing and Daedric Smithing.
Do I need to need to take Glass Smithing and Daedric Smithing if I want to learn the Dragon Smithing perk? Either or? Neither (as long as I have 100 smithing)?
