I've recently been playing a bosmer archer type character, who uses only enchanting, archery and sneak. he only uses clothes (because i think light armour is too chunky and some of it looks like heavy armour).
I have 67 enchanting and i was wondering does the 'insightful enchater' perk effect enchanting to my clothes? as it says skill enchanting to armour are 25% stronger. Is clothes classed as armour?

or would i be safer off taking the enchantments to weapons are stronger route? as i want to get the 'extra effect' perk (2 enchaments 1 item).

Whats your opinions?
btw this build is great fun! and real challenge.

Affects clothes and armour equally. If you stick with just fire for weapons, and get to dual through the other branch, you can get good clothes and weapons for a more efficient perk expenditure (4 for insightful, corpus, extra effect and fire, vs. 4 for fire, frost, shock and extra effect).

Applies to clothing too.

you are an archer, so most important thing for you is probably fortify archery enchantment. insightful enchanter makes that enchantment stronger. and fortify sneak will gets better too. around level 60 is when I start making ability enchantments after taking all available strength perks. You need grand soul gem for it to be good. fortify archery enchants are 37% when maxed out. It will give you up to +148% damage with your bow.

Before level 60, skill enchanting is too weak to be a good deal for me. In early levels, I use enchanting mostly for enchanting weapons. Weapon damage is not negatively affected by using smaller soul gems. Only the charge capacity is affected.

clothes are same as armor for enchanting purposes. big difference is that if you wear all clothes, your armor rating stays at 0 and it will not level up your armor skill if you get hit. also for a mage, the mage armor perk only works if he has no armor on.

Thanks helps alot!
