One could hardly expect anything than an overdramatic entrance from Siobhan. She had not gotten where she was because of common sense. Actually, her achieving anytihng had all to do with her being good in bed and good at destroying things and nothing else. Sometimes that was enough to become Exarch - not that she had done anything as one other than death charge across Gehenna - and then company vice president. But perhaps she would not survive, which would be no loss.
Contrary to popular belief and Omega/Firemane propaganda bolters were not I-win-cards. Undoubtedly powerful, but they had low ammunition capacity and a slow rate of fire. They were also not that effective against beskar'gam unless they hit one of its weak spots, though getting bombarded by several was obviously still unpleasant. Of course, the common tactic of a force-user, namely trying to deflect rounds, was counterproductive against explosive bolts because it blew up in your face. But Siobhan barely used a lightsabre anyway. Telekinetically shoving rounds was ill-advised as well though.
Regardless droids emerged and wasted no time opening fire with their guns. If Siobhan had the time she would have wondered where they had gotten bolters from. Something to...look into because this writer strongly doubts Archangel's involvement will remain totally secret forever. Enhanced speed would...not be very effective, so when faced with the choice of drawing upon the Force to shield herself or having something else bite the bullet,
Fortunately, there was lots of debris lying around. She tugged Tempest into cover as she raised chunks of debris and bodies and thrust them forward as improvised shields against the rounds coming from above and at the far end. The shield was far from perfect, especially due to the lack of time and was blasted under the pressure as explosive bolts impacted. Siobhan was struck hard by the blast, though the effect was mitigated, and exerted herself to scatter the debris to the winds as it broke into pieces, shards of shrapnel raining down upon her.
She was painfully thrust back by the shockwave and suppressed a cry of pain as she was struck in the joints, shrapnel having found a chink in the armour. Inexpert Crucitorn kept her functioning and made her stifle the white hot pain, for now, though the shard embedded itself. Another viciouslyGiven the beskar'gam being hit by the blast was a bit like being struck with a hammer.
By and large it could not pierce the armour, but it bloody hurt. Her shoulder down to her organic arm felt immobilised, her armour was scorched. "I'll draw their fire!" Enraged as she was knocked to the ground she reached out to send a shattering force repulse towards the droids, aiming to engulf them. A wide area of effect torrent of lightning came shrieking from her fingertips.
