'Well shoot I only have a few options for this. Lets hope these things payoff as planned.' Jeff said as he released charged electric energy that he stored into his gauntlet earlier in hopes to shocking the fuck out of Sera who was stupid enough to grab hold of his chain. On the premise of that not working Jeff took aim with his other gauntlet and fired off a point blank grenade on Sera that was designed with a special property to them. "Let see how you handle this 'useless tech'! GO!! TEMPLAR BOMB!" 
As the name would specify, this grande was something Jeff whipped up with the initial design for shutting how all arcane energy in a decent blast radius while creating a smoke screen that would blind the soon to be weakened mage. He only had 2 on him though, as they were not the easiest things to make, so he had to make sure the attack would count. With luck it would disable that magical blade of his along with any force fields he was conjuring up just leaving that armor of his to tank any blows.
