I was wondering, as a pure Archer with 85 in Archery, would it work if i ever wanted to use a bound bow instead of an actual bow?
1. How much magicka is required to summon a bound bow? (i have like, none)
Bound Bow is an Adept-level spell that costs 183 base Magicka. The more Conjuration you have, the less it'll cost.
2. Do you need a certain number of perks invested in conjuration, or a certain level of skill in that tree to summon one?
No perks required, but you do need a certain skill level to be able to buy the Spell Tome. I think around 30 or 35.
3. Is the damage of a BB based on your skill as an archer? or the level of the spell?
It's based on your Archery skill and anything else that effects Bow damage, but can also be increased with a perk in Conjuration called "Mystic Binding".
4. How long does a conjured BB last for?
Default is 120 seconds and can be increased by using potions with the Fortify Conjuration effect, and/or by the Dual-Casting perk. Normally this is enough time for you to regenerate your Magicka back even if you're in combat.
5. are there limited arrows that come with a conjured BB?
Yes, you get 100 Bound Arrows that add 24 damage (Daedric/Nord Hero level). Generally the Bow will disappear before you run out of arrows.
