Attribute point spending

Increasing Attributes - In addition to learning more skills to expand your strategic options, you can also spend attribute points to gain ranks in the attributes linked to those skills so they are more powerful.

To spend your attribute points simply go to the hero tab by pressing "H" or clicking the roll-out menu tab in the bottom left corner of the screen and selecting "hero". (Note: Due to the recent patch, it is now "K", not "H". This can be changed in the options menu.)

Take a look at how many unspent attribute points you have (listed as "Attribute Points:"). Now look at the bottom of the hero tab where it lists all your attributes; the attributes listed there are the ones you can put ranks into. If you want to increase an attribute by a rank simply click on the right most "arrow", which is pointing upwards, next to that attribute's name; the number displayed on that arrow before you clicked it will be deducted from your unspent attribute points, and your number of ranks in that attribute will increase by one.

Repeat this as you see fit, increasing any attributes you think you may want to use skills from and keeping an eye on your unspent attribute points; if, for example, you only have 5 attribute points left but it costs 6 to move to the next rank in one of your attributes you will have to make a choice between refunding a rank from a different attribute or foregoing getting that extra rank. Make note that while it's often better to specialize on 3-4 attributes rather than spread your points out over 5+ attributes, specializing in only one or two may not be ideal because of the attribute point cost scale.

First, let's see how points are spent:

One attribute
As you can see from the table above, attribute spending starts at a 1:1 ratio, and gets gradually more expensive as we progress through the ranks. It's pretty linear up until rank 7, where going from rank 8 up to rank 12 gets increasingly expensive. We can see that from rank 0 to rank 1 costs 1 point, where going from rank 11 to rank 12 costs 20! The bottom row of the table displays the overall cost of attaining the particular rank from 0. So, for example, to bring an attribute to rank 12 from nothing, would cost us 97 points total.
