A Few Armor Questions

I have a few questions regarding armor, shields and weapon mods.

First of all armor. Now my confusion is with "+10armor vs physical". Is this +10 AL to physical or some other kind of armor scale? So like usual AL 80, Al against a phys attack is Al 90?

Now with shields and weapons. Again the question of these mods "+7 vs physical", is this Al or something else? And if something else can you explain how it calculates in with the damage calculating. The other part for shields, with "-10 dmg from projectiles" is this exactly -10 points of damage? So an attack thats going to hit for 60 becomes 50?

+10 Armor vs phys means if that piece of armor gets hit with physical damage then it will have an additional armor added to it (ie 90 instead of 80 or whatever)

mods with +5 armor/+7vswhatever adds an additional 5 armor to whatever piece of armor gets hit.

There's nothing with -10 dmg from projectiles, I don't know what you're on.

Thanks for the answers. Yeah that's my bad I was getting mixed up with Geoffer's armor+10 vs piercing...

I meant the -3 dmg while hexed or what have you

-3 damage while hexed means that when you're hit for any damage while you have a hex on you, the damage will be reduced by 3 points, regardless of what type of damage it is, as long as it is damage in some way.

Okay thanks that's great. One more thing, this regarding infusion. Is it global? I have 4 suits of armor for my war, if I did an infusion run and put on 1 piece of armor from each of my sets on and get infused would my sets all be ready for mursaat orr do I have to infuse 4 times?

you'll have to be wearing the armor to have it infused, so you'll either have to do the infusion part of iron mines for each set or,[I've never checked this] talk to the seer once you give him/her the stuff each time with the different armor sets on
oh and for that last question, each armor piece has to be infused for you to take humane damage from mursaat, I don't know if having only one piece infused will reduce the damage by a ammount, but I know that even with all but your head armor infused, you'll be taking alot of damage[don't ask, I learned it through experience]

Yes, each piece has to be infused to take the full effect. If you have four pieces infused and one not then you will be partially infused - you'll take more damage from Spectral Agony than having five pieces infused but less damage than having three or two or less pieces infused. You can check here for the damage details.

You can only infuse the sets you are currently wearing when you talk to the Seer. You cannot wear one set, get that infused then change armor and get the second set or piece infused. So for each infusion attempt, you can infuse up to a maximum of five pieces of armor. So you will have to do it four times, one for each set.

Haha yeah I can do that...But I also have 2 different arms per set (1 axe and 1 sword)! Ouchers....
