If you are planning to play as stealth character you should consider dropping Light armor skill or Heavy for that matter, because as stealth character it will level very slowly. Take it from me I'm playing with 48 level stealth character on legendary and I wear heavy armor just for looks you know to look good in it... I think now my heavy armor skill is at 30 something like that.
The reason is because I get rarely hit and if I do get hit I mostly die because the only left are high lvl enemies at that moment.
Now if there is particularly light armor you like and you would want to enchant it I suggest you to make it your secondary skill and spend only 4 perks there:
- Agile Defender 1/5 = armor rating 20% more
- Custom Fit 1/1 = wearing all 4 pieces of light armor 25% more armor rating
- Unhindered 1/1 = armor is weightless
- Wind Walker 1/1 = 50% faster stamina recovery if you have all 4 pieces of light armor
Unhindered perk is useful and Wind Walker is very useful specially for archers when using Eagle Eye which consumes a lot of stamina so you would want to replenish it as fast as you can. And is good for long distance running (escaping
).
