You have the opportunity to take any class ability from any class and use it on the character you are playing now.
The ability retains all of its original attributes (you can't make a magicka ability a stamina one) but you cannot bring over any class passives.
Personally, I'd love to have Biting Jabs on my Stam Sorc. Even without burning light, I feel like it would be an amazing damage tool in PVP, and given that Stam Sorc lacks any damagaging abilities of its own, I feel like it would be the strongest choice.

I play a character called "Gives Me Wood Elf" because I am a mature and sensible person.
