Well, considering Thara is a 30% reduction and Ogretooth/Tirfing is a 25% reduction +1 def....

With your other gears listed:

Top head gear - 10% reduction to demi

Weapon - 10% reduction from demi

platinum shield - 15% from medium

You've already got 20% demi-human, and 15% medium.

If you can double stack the same card in a shield:

Double Thara would bring you up to 80% demi-human and 15% Medium reduction

Double Tirfing would bring you up to 20% demi-human and 65% Medium reduction, plus 2 def.

Thara and Tirfing would bring you up to 50% demi-human and 40% Medium reduction plus 1 def.

Here's the math:**Double Thara** = 1.0 * 0.2 * 0.85 = 0.17, or a total of

**83% damage reduction**.

**Double Tirfing** = 1.0 * 0.8 * 0.35 * 0.98 = 0.2744, or a total of

**72.56% damage reduction**.

**Thara and Tirfing** = 1.0 * 0.5 * 0.6 * 0.99 = 0.297, or a total of

**70.3% damage reduction**.

Don't forget that your def is also going to reduce your damage received by a % also.

Pre-Renewal was straight up def % reduced. So if your gears gave you 37 def. You'd have a 37% damage reduction.

So just tack that on in the formula, and you'll have a good estimate of your damage reduction.

General idea is that everything stacks additively with itself, and multiplicative with everything that's not it.

But it figures based on damage received....so an 80% demi-human reduction would get figured in as 20% damage received from demi-human...

Hence the 0.2 in the double Thara formula.

And then VIT is subtracted from the very end.

So, ([Total Race]*[Total Size]*[Total Element]*[Total Range]*[Total def]*[Assumptio]) - Total VIT = Total damage

It's not the prettiest representation of the formula. If I took more time, I could make it complete and in proper math.

But it gets the idea across.

That's why your Tank classes have high VIT. VIT without def doesn't reduce much. But if you have 70 def, and some % race/size/element reductions...that 1000 damage is coming down to 150ish....then you subtract out 100 VIT....and you're only taking 50 damage per hit.

That VIT is acting like another 67% damage reduction.

If you do switch to that Valk Shield....just subtract 15 from your [Total Size], and add the 20% Water reduction to the [Total Element] in your formula....if you're taking water damage. If you're taking Earth damage....obviously the Water Element reduction won't factor in.

So unless you're only getting hit with Water or Fire; I'd vote to stick with the size reduction from the Platinum Shield.
