Greetings
The strengths of the Dwarves could be strength and endurance both mental and physical, tenacity, craft skills related to stone and metal, and be people with a high sense of honor and commitment.
Weak points could be their stubbornness, distrust of the "inferior races" and their eagerness to accumulate wealth.
I know they are very topical concepts, especially related to the Warhammer Dwarves, but I like it, hehe.
See you
