How much Knock Back protection should I have?

If you're a ranged AT or a Spider you'll need to build for KB protection. Acro will give you 9 points base (enhanced up to 11 but generally not worth it) and you'll want to put in some Karmas and Steadfasts to get yourself to at least 41 points and preferably 45-47 points. 41 will stop anything short of Force Bolt or other high-mag KB powers if they're weirdly slotted but I don't know that anything will get through 47 points.

Almost all power effects have two properties: a magnitude and a duration. Damage has a magnitude, but it typically does not have a duration - it has duration zero. Damage with a duration is not a DoT: damage with a duration is a continuously firing damage at the maximum speed the server can calculate damage - about eight times a second. Damage with a duration is generally a bug. Mez, on the other hand, tends to have meaningful magnitude and duration. Its important to note here that only *one* of those two properties can be changed for each effect per power. When you slot a hold for hold enhancement, the hold's duration gets longer. Its magnitude does not get higher. That's because all holds are designed so that the hold effect is *tagged* to be "Duration type." That means strength buffs affect duration, not magnitude. This is a binary switch: it can be set to "Magnitude" or "Duration" but not both. All effects in all powers must obey this rule: one property is frozen static, and one can theoretically be changed by buffs and debuffs, enhancements and other powers.

KB (and KU) are different from most mezzes. They are not designed to have duration, and buffs don't boost duration, they boost Magnitude. So while most holds are Duration-type effects, KB is a Magnitude-type effect. Buffing KB buffs its Magnitude. And KB is a Cur effect like most Mez and like most Mez protection.

Interesting note: you do not need to factor DR into mez magnitude to determine if something is mezzed. You only need to factor in mez strength in the attacker's mez power itself. The reason: Rule Two. DR only affects totals. If you have a mez protection power that is reducing Hold by mag 10, and and you have an incoming set of holds that are mag 9, the total is -10 + 9 = -1. DR might reduce that, but it will still be negative, which means you are still not mezzed. If the incoming hold total is +12, then the total is -10 + 12 = 2, and you're mezzed. DR might reduce the 2 to a lower value, but it will still be greater than zero. The only thing you have to factor in is if the attacker has mez strength capable of increasing the magnitude of the mez. The answer for most mezzes is usually "no." Enhancement and other buffs make holds last longer, not get higher mag. But the exception is KB: buffing a KB will buff its magnitude, so you do have to factor in KB strength into the attacker to determin the attacker's net KB, before adding to the target's KB magnitude protection.




For the mathematically inclined, here's the formula:

Final Value = Original Value * (1 - ABS(ATAN(A * Original Value) * 2/pi * B))
A and B are the tuning parameters set per attribute, per aspect, per archetype. To find the values for A and B, see the DR calculation sheet at this link: https://spreadsheets.google.com/ccc?key=0AiQEKoD191W7dFJUT0hyT3pGeGo4NXpsTGE4TzFZU Xc&hl=en&authkey=CPO10LgM

Use the two pulldowns to pick archetype and attribute, then enter values in the Normal value column for Strength, Cur, or Res. The calculated values show to the right. For reference, at the far right the sheet displays the A and B values for that attribute, that aspect, for the selected archetype.

Correct.

Anyone know if the Widow Indom Will still suppresses when mezzed?
