As Marius leaps, the beast escapes his strike by a few feet. His body twists in the air as he returns and lands safely on his feet.
Hagadark uses his size and strength, taking the beast by its tail, but it is not enough! The wyvern pulls and, by a short victory, escapes Hagadark's grasp! As Mhuagra's words reach the creature, it is blinded, but it profits from the open path upwards and flies, strong and fast! It ascends some thirty feet, moving a bit forward as well, but not before being attacked on its flank by Hagadark, right beneath its wing! The beast seems to be weakening, bleeding profusely and with several burned scales. If the attacks continue, it knows it won't resist, and so it seems resolved to flee the battlefield, taking Morgrym with it!
"STOP THAT, BEASTS, OR I SHALL SLAY THE SMALL ONE HERE AND NOW!" - the wyvern threatens, closing its grasp on Morgrym!
[Well, the wyvern managed to escape, but it took a good deal of damage so far... It's blinded, but it still manages to move normally upwards, 30 feet up and 30 feet away - total of 60 feet for normal movement. I have considered several bonuses for Hagadark as well, in order to determine if it would be impeded, but it still rolled quite high]
Klutha slays yet another mage with a strike! Ho-og responds to the ray with a precise and destructive attack, leaving the body of his attacker to rot... Bloodthirsty, it advances towards another Yuan-ti, cutting the creature in half with a single strike! Around it, the unfortunate shots for the archers are sprung out, crowning the corpse left by the orc fighter.
The remaining mage is surrounded by dwarves and under Klutha's murderous shadow. It seems to know she'll kill him, and it attempts one last ray, rooting for it to kill her. Klutha escapes by the skin of her teeth and quickly responds, delivering a bestial strike that cuts the creature's head off!
Without any mages left, the orb of fire is dismissed. Now only the two warriors charge, both against Hagadark! Of all the attacks delivered in quick succession, only one hits the shaman, cutting deep on his back!
In the back, the warriors under Mhuagra's spell are openly fighting against one another!
[Ok, this one was a vigorous one! 8 points of damage. I took the liberty of redirecting Ho-og, since Klutha one-hitted AA15. Ho-og kills one mage with the OA Neurotic mentioned - I didn't see any rolls on @MetaVoid 's list, so I rolled - and I used his roll against the second closest mage. Klutha's OA brought the other down and now we have two standing warriors. The others are still confused. Next we have @Neurotic, @KahlessNestor and @Shayuri. Remember that you don't have much time! Next round the beast can go up another 60 feet, if no one stops it! Also, @KahlessNestor, you can try to break free while Hagadark holds the wyvern down. I guess it would make more sense than just allow your action to be rolled later on, since the grappling struggle would last for a few moments, at least. And I almost forgot: can you roll a wisdom test for me, please? ]
