Well, you can check your talent and power page. The stat that you got at the beginning should be listed at the "talents" section of the page. In case you do remember what world you picked, Marleybone: +5 accuracy (keen eyes) Skull Island: +5 dodge (born sneak) Mooshu: +5 damage (born warrior) (I'm pretty sure that these are right, but I may be wrong.) Grizzleheim: Adds health (naturally tough) (I forgot how much health it gives.) Krokotopia: Adds to spooky effects (naturally spooky) (I once again forgot how much it adds.)
This should let you know when you open up your Powers/Talents page (P). Click on the star in the upper right corner to go to the Talents (all trained spells) and the first one should be your Keen Eyes, Naturally Spooky, Born Warrior, etc.
