+2 is what you can find on an early-game magic item.
damn, over 30h of game, I really had crappy loot xD I had to wait the end boss to get proper items
Anyway, back to topic, +2 on one stat will really have no weight over the length of the game . You can still choose to make a dwarven mage, the impact will be minimal, really.
Speakin of racial skill, "Encourage" for human, given free and using no memory slot, is overpowed

I like the skill, but it should be back to the warfare skilltree I have, however, no idea what could be a good racial skill for human ... Maybe something like "iron will - ignore death for X turn - dies at the end " ? Na, too OP
