A Paragon interrupt
"There Can Be Only One!"
Cost :5 Energy
Cast Time: 1/4 seconds
Recharge: 20 seconds

Target foe is interrupted and struck for 10...29 damage. If Target foe was casting a spell at time of interrupt, "There Can Be Only One!" is replaced with that spell for 5 ...... 12 seconds.
It would be up to the Guild Wars staff if it would be able to copy and Elite skill or not. Post your opinions.
