So, flat armor reduction seems a little wierd (what with being able to have NEGATIVE armor), so I did some calculations with Taric (which led to some Soraka calculations as well) to see how much flat armor reduction you could get. I am not perfect, so I may have made a mistake. If so, please comment so that I may correct it.

Team Composition:

Top: Nasus (40 armor reduction with rank 5 Spirit Fire)

Mid: Soraka (Gives Taric 320.7 armor with Astral Blessing)

Jungle: Rammus (30 armor reduction with rank 5 Puncturing Taunt)

ADC: Corki (40 armor reduction with rank 5 Gatling Gun)

Support: Taric (25 (+5% armor) armor reducting with rank 5 Shatter)

Let's see how much armor can be reduced with Taric

Taric's base armor is 16.5 + (3.2 armor per level) = 74.1 BASE armor

Taric gains 30 bonus armor with rank 5 shatter

Masteries: 0/21/9 or 9/21/0

Notable Masteries:

Hardiness: +5 armor

Legendary Guardian: +4 armor and MR per nearby enemy champion (assumed to be 20)

Enchanted Armor: +5% BONUS armor and MR (added last)

Total flat armor from Masteries: 25

Total Bonus armor: 55

Total armor: 129.1

Runes:

0.91 armor Marks (0.91 * 9 = 8.19 armor)

0.15 armor per lvl Seals (2.7 @ lvl 18 * 9 = 24.3 armor)

0.7 armor Glyphs (0.7 * 9 = 6.3 armor)

0.38 armor per lvl Quintessences (6.84 @ lvl 18 * 3 = 20.52 armor)

Total armor from Runes: 59.31

Total Bonus armor: 114.31

Total armor: 188.41

Items: Max Armor (This is just to show the maximum reduction)

Thornmail x6: 600 armor

Total armor from items: 600

Total Bonus armor: 714.31

Total Armor: 788.41

Buffs:


 * Astral Blessing: +320.7 armor

Total Bonus armor: 1034.31

Total armor: 1108.31

Bonus armor from Enchanted Armor mastery: (1034.31 * .05 = 51.7155)

Total armor: 1160.0255

Total armor reduction from Shatter: 25 + (1160.0255 * .05 = ~58) = ~83

Total armor reduction from team: (83 + 40 + 40 + 30) = 193 armor reduction

The rest is just for fun.

Total armor: 914.11 Bonus armor from Enchanted Armor mastery: (914.11 * .05 = 45.7055)

Total armor: 959.8155

Total armor reduction from Shatter: 25 + (959.8155 * .05 = ~48) = ~73

Total armor reduction from team: (73 + 40 + 40 + 30) = 183 armor reduction
