Greetings
The strengths of the High Elves could be swiftness, agility and, of course, their artistic abilities.
Their weak points could be a certain physical fragility and a total lack of empathy towards the less long-lived races, sometimes showing condescending or haughty.
His arcane abilities and superior intellect could be both his strength and weakness. Powerful sorcerers are often victims of their own arrogance.
See you.
