If you don't intend to reduce the upgrade later, you can use an Attribute Bonus ability that doesn't show an icon, and an upgrade based off Skeletal Mastery that increases the level of the Attribute Bonus ability.
I would not advice to use the attribute bonus ability in this case since it is just unneeded overhead, unless you want to increase the stats of multiple heroes owned by the same player at once.
If this is for just a single hero you should better not use any ability at all.
This is because you can manipulate the attributes of heroes directly with triggers, setting, increasing and subtracting attributes at will. No need to waste additional memory for ability levels and effects.
If you trigger an attribute increase, you can't detect the amount of bonus attribute a unit has, as it changes the base value instead of adding on to it. Nor can the player tell how much his attributes have increased - he only knows that he has higher attributes.
I am working on getting access to the old news portal under a different URL for those that would rather use that for news before we get a different news view.
It is OK though for the main page to open up on the forum in the view it was before. As long as the portal has its own URL so it can be viewed that way I do want to try it as a regular forum view for a while
I switched it to a "Standard" article forum. This will show the thread list like normal, but the threads themselves will have the first post set up above the rest of the "comments"
