Beta Skill Points

Is there something, a tool or a formula to see how your sp on a piece of armor will change after update?

Example: this vaward has 24sp out of 35, after update Vaward will be like this with 25sp as max

So how can i see how many sp will my vaward have before the update takes place?

EDIT: I tried with a simple proportion where 24:35=x:25
x = (24*25)/35 = 17.1428571 --> 17sp after update
but im not entirely sure

 

You'd have to look at wynndata, isolate the range of possible roll values for each stat, and map that to the post-revamp base value. You can't always get a one-to-one mapping - e.g. a current Libra with 10sp in a particular stat could be either 7sp or 6 sp after the change. Although, in this particular situation it's relatively easy to tell because of the stars - 10*** will become a 7 while 10** or 10* will become a 6.

 

First of all, you should know how ids are rolled. Then there are Modpacks like this which show you the exact percentage that your ids rolled. And the last thing you need are the base values of the ids of the updated version of the item. The get them, you need to guess a little bit while keeping in mind that they are always integers.
For example, if we look at the skill point ids of the updated vaward, you see that they have a range of 1 to 5, so the base value has to be 4, as it results in a maximum of 4 * 1.3 = 5.2 --> round down to 5, and a minimum of 4 * 0.3 = 1.2 --> round down to 1. A base of 3 isn't possible as the maximum would be 4, and with 5 it would be 7.
With your percentage and the base value you can simply calculate the new value. For example, if the mod shows a 80% next to your strength stat, your new strength will be 0.8 * 4 = 3.2 --> 3.
