Hi. I recently got a Stygian dagger drop from an npc in reapers March, and I thought the set ability was cool, (+20% spell damage when stealthed.) so I bought four more pieces of the set off of guild stores. Now that I have the set of five, I have tried to go into stealth mode and cast a spell at an enemy, but just when my cast animation ends I'm detected and I don't get the bonus 20% spell damage. I was wondering if someone could tell me why it isn't working.
I am a sorcerer, and all I did was, go into stealth and cast crystal fragments at an enemy.
I am using it in combination with the storm calling ability that increases weapon and spell power, (I forgot the name) and some passives to further increase the damage.
