Their only skill is Sketch/Copy, which either copies the last enemy skill used or (if we're taking the Blue Mage approach) puts them in a stance where they copy the enemy skill used against them. Their stats are generally mediocre-average, with a focus on Spd to Sketch/Copy skills easier. The rest of the Hero's slots are filled with stolen skills, up to a maximum of 7. The Hero will have a Camping skill that lets them delete a skill, for easier customization.

Assuming enemy skills are taken 1 to 1, what would be the most useful?

One of the best feelings I've had with open world games is looking out to the horizon, seeing a structure in the distance and saying "What is the heck is that?". I want an open world game with lots of structures/dungeons to explore, ideally with decent combat and character customization. Something like Dragon's Dogma: Dark Arisen.

I tried Tainted Grail, but it ran pretty badly on my computer, so low-end recommendations are welcome. Thanks!
