Are the modifications to the effect of the tumble skill posted anywhere? If not could someone fill me in.

Thanks.

From what I can determine, armour check penalty is applied to tumble. The resulting value must be over 5 to get the AC bonus.

ie. Tumble of 7 -5 for breastplate = 2, so no tumble AC bonus.

Thanks.

ie. Do you get the full AC bonus that you would normally for your ranks in tumble if your modified tumble is over 5, or do you only get +1 to AC for modified tumble between 5 and 9, +2 for modified tumble between 10 and 14 (if your modified tumble is less than your ranks). Is skill focus or a bonus from items counted in the calculation?

Thanks again.

The way tumble works is like this.

You take 20 ranks in it and wear heavy armor and a tower shield. The heavy armors and shield gives decreases to the tumble checks but not to the skill so you would still get the 4 AC from taking tumble. It wouldn't help you running around that much though.

I don't think that's quite right. It's been modified for EfU but I'm struggling to understand the modification.

Arkov's post should explain it.

You get +1 AC per 5 ranks assuming the ranks you have are positive. So it's certainly possible to get tumble AC in fullplate, it just requires having tumble sufficiently high enough to beat the AC penalty.

No, negative armor modifiers do prevent AC bonuses.

If you have 10 points in tumble invested, then the positives and negatives add up to form a modified tumble score. If it's 9, you only get AC +1.

That's why large shield +1 AC (+3 total), and only a -2 armor modifier compared to the standard Tower Shield (+3 total) and - 8 modifier - is so valuable to builds that invest in tumble and are heavy melee.

Not sure about skill focus though. Assume it counts.

What you have said seems to differ from Arkov's post: "As of v616, Tumble AC is now calculated based on the lower of your effective ranks and your base ranks, rather than only on your base ranks."

That previously quoted sentence seems contradictory to what he quoted above that sentence: "bonus from Tumble only applies when you have the effective skill ranks to back it up -- so a Fighter/Rogue wearing full plate and carrying a tower shield, and thus having a large penalty to Tumble putting him below zero effective ranks, will no longer get an AC bonus from his base ranks in Tumble." This last sentence seems more in line with what you have just said.

It seems that in the same post he is saying that 1) you get your tumble AC calculated from skill ranks if your modified tumble skill is positive, and (quite differently) 2) your tumble AC is calculated based on modified ranks, ie. modified tumble 5 grants +1 AC. The last statement in the post is the first interpretation I have made, which is different from what you have said. It's probably just me.

Thanks for taking the time to explain it to me.

(Tower shields get -10 modifier.)

Right, that's how it works right now. Modified tumble is used to calculate the AC bonus.

BUT this statement:

"bonus from Tumble only applies when you have the effective skill ranks to back it up -- so a Fighter/Rogue wearing full plate and carrying a tower shield, and thus having a large penalty to Tumble putting him below zero effective ranks, will no longer get an AC bonus from his base ranks in Tumble."

seems to imply that if your modified tumble skill is positive then you should get what your base ranks would give you normally as an AC bonus. See what I'm saying?

I think you're just misinterpreting his sentence. 1 Tumble AC per every 5 base ranks assuming your effective tumble skill (taking into account armor penalties) is greater or equal to 5 (or 10 for 2, etc.)

If you have ten base tumble, but -5 from AC penalties, you will get 1 bonus AC.

If you have 10 base tumble, but -8 from AC penalties, you will get no AC bonus.

If you have 5 base tumble, but +10 tumble boots, for a total of 15 effective tumble you will only get 1 AC.

So skill bonuses from items/feats is useful in neutralizing the AC penalty, but you still need the base ranks to get the AC.

Does that explain?

Yes it does. Thank you.
