Knightfall
World of Kulan DM
Cover increases the creature's AC. It doesn't decrease Tim's attacks.Since Big Tim doesn't have to move, he simply attacks with his sword. He doesn't try to dual wield with the shield, since it doesn't seem to be very effective. He simply concentrates on using his blade to flay the flesh of the beast.
Attacks: Hit AC 22, 33, and 33. (If beast has cover, then Tim hits AC 18, 28, and 28.)
Damage: 14, 15, and 20.
All rolls have been submitted via Facebook Messenger.
Your first attack is a miss, but the other two are hits.
1st Sword Attack vs Beast: 1D20+19 = [3]+19 = 22 (miss)
Second Sword Attack vs The Beast: 1D20+19 = [14]+19 = 33 (hit)
Third Sword Attack vs The Beast: 1D20+14 = [19]+14 = 33 (hit)
---
Damage vs The Beast Sword Attack Two: 2D6+10 = [3, 2]+10 = 15
Damage vs The Beast Sword Attack Three: 2D6+10 = [4, 6]+10 = 20
Rockhorn is making sure he is beyond the creature's reach, so he isn't threatening The Beast. He and his mount are flying high above the creature. While flying he and Spritewing must continue to move forward while attacking. I don't think Spritewing has Hover.Oh wait, if Rockhorn is flanking, then even with cover, Tim hits AC 20, 30, and 30.
