Question about Arctic Armour.

How does Inner Force work with Arctic Armour? The wiki say it should boost it, but the tool tip shows no change. Is there any way to tell? since there nothing on the character sheet to check it against.

The tooltip is just bad. As far as I'm aware, Inner Force never affects tooltips. But it does work on all parts of Arctic Armour (mana costs included, remember!). The damage reduction might show up on your character sheet when it's turned on, and that should show Inner Force's effect, but I can't remember off the top of my head and I'm not in a position to check.

No, it doesn't show the increase on tooltip and it shows nothing of your character sheet. We kinda have to believe GGG on that there is a defensive upgrade. The mana cost definitely goes up, and by a lot.

Thnx for the reply's, if any math wizards know a formula I could use to figure out the physical reduction and mana cost of a level 24 Arctic Armour with Inner Force that would be great.

It's simply 1.21 * the listed number (or 1.26 if you have Devotion too). The wiki has mana cost numbers for AA with Inner Force up to 28, as well. It's ~324.5 mana/second while moving, but the wiki doesn't list DR values for level 24 so I can't help you there.
