The battle system has been updated with automatic skill learning. Similar to casting spells, you gain skills as you learn from each round of battle. Being hit teaches you a little about how to dodge better. Missing teaches you a little about how to aim better. The more you learn, the harder it is to learn more.
If you feel combat is too slow, try attacking again. Double your pleasure.
One you have achieved level 1 mastery, you will no longer learn until you find a level 2 trainer. But alas, there aren't any just yet. There's always something to look forward to, no?
However, there are now a couple of level 2 creature templates to spawn. Bring it on!
