Jericho was not the first out of the Chimera, both Ogryn and Sergeant leading the charge as he made his way out, right behind Tasha as she led the way for the Psyker. Ripper and lasgun fire was already doing a rather impressive show on the Orks that had jumped up at the chance to attack the newfound enemies, even sending one down onto the ground. Jericho was moving when he saw the stikkbomb sail by into the compartment of the Chimera and the roar of a detonation, plus fire and shrapnel, flew out of the crew compartment. Well, that was two down already, the Psyker thought with a mental shrug, turning as his lit up with sparking blue lightning, reaching his will out to the Warp, drawing in his full power. It was dangerous to do, not overly defining the paths and flow of the warp flowing within him, but hardly as dangerous as overdrawing himself. The Emperor was with him, as his power manifested far better than it normally would, as the bomb lobbing Ork was about to find out.

Tasha was more focused on the Psyker, as soon as she realized what he was doing, than the Orks. Anytime that man did anything more than breath, he was asking for trouble. But, thankfully, his powers manifested without unusually weird or abnormal effect. As much as twin lashes of bioeletric lightning arcing across the battlefield, right towards the offending, bomb lobbing Ork could be seen as normal. Sure enough, the blasts of lightning slammed straight into the Ork's chest, searing both hide and armor with seemingly little effort. The Sergeant's battle cry was clear as Jericho followed close behind, his attack unleashed successfully. 

"The warp flows strongly, brothers and sisters, these greenskins aren't going to last overlong, rest assured!"
