The Ranger in question had his bow ready for action, wondering exactly how to react against the now vanished shadow-wielder, who had taken the fool kid with him. But with the monster definitively determining that getting after them would be a problematic proposition at best, and now focusing its full attention on him with a blind rage, the Ranger decides that present dangers are far better dealt with first. It had bitten off its own arm to heal its other injuries...interesting. And it was making itself a difficult target...naturally. Of course, being an expert marksman, generally Cruallassar would have no problem hitting even a quickly and erratically moving target, without bad luck intervening...but with the monster's proven reflexes and speed, there is no guarantee that it could not dodge his shots as he fired them. Of course, he had a solution for this problem. Two hailstorm arrows flew at the primal vampire within as many milliseconds, scattering their swarms of energy projectiles almost simultaneously, with three explosive arrows nocked for the next volley in the next instant, the elf crouching and renewing his momentarily relaxed speed enchantment in preparation for further action. An unnaturally strong and fast bat-like monstrosity vs an elite Rangermaster? Barely a contest.
