[Item Concept] Force of Nature

##Force of Nature

• Cost: 2900 Gold
• Recipe: Spectre's Veil + Aegis of the Legion + 600 Gold
• 35 Armor
• 60 Magic Resistance
• 250 Health
• UNIQUE Passive - Fortitude: While near an enemy champion, moving and impairing movement builds up stacks of Fortitude. Fortitude blocks up to 20% of all untargeted damage at 100 stacks. Stacks decay when they aren't being built.

An item for Tanks so they don't die to the surround-sound damage. It's great because the damage reduction can't be ignored or reduced by enemy carries in the late game (unlike Armor and MR).
