Thoroncir coordinates with Felareth & Bitur . Once Bitur casts the Spider Climb , ride forward and grab Felareth from Gilraen’s horse. This will drag Bitur & Grávund with them.
Hejren casts Mage Armor bringing her AC to 17.
Ceol begins his charge towards the Uruk Hai group 2, he gets up 30’ waiting for them to swarm him.
Gwaelur awaits the Fly spell from the Canath Mandolin of the Hobbit Bard Felareth.
Ghân blasts group 4 of Uruk-hai about 90’ away that are packed close charging downhill. His bolt does 15 to 3 of them. All fail their Dex save of 15.
Bitur casts Spider Climb and hangs on tight to the disk.
Felareth plays up a Fly spell on Gwaelur & Thoroncir kicks into highspeed charging into the first group of Uruk Hai with Gwaelur fly low to the ground just behind them. He also inspires Thoroncir.
Thoroncir uses inspiration on a 5 roll and successfully charges two of them with his action surge 2 are already dead.
Gwaelur takes 4 swings using his action surge. He has advantage in the first round vs. orc-kind. So uses Great Weapon Master every swing. He easily dispatches 2 Uruks leaving only 2. No need for maneuvers yet. He uses his bonus action to set up tunnel fighter between the remaining Orcs and his friends.
Baygir trample the 6th Uruk knocking him prone for a total of 26 damage. Grávund hits this one for 8 more ending it.
The final Uruk moves past Gwaelur to get to Baygir giving Gwaelur a free opportunity and then Gwaelur uses tunnel Fighter to use his reaction for an attack. All this is still with advantage as it is still the first round. All 6 Uruks are destroyed.
Meanwhile the Ceol meets 6 on his own from group 2. Leofwin tramples one for 22 damage and it is prone. He swings, hits and smites dropping 1 and hits the prone one finishing it off.
16 arrows fly at Gwaelur . The Hunter Killers hit 4 times but the other 4 archers are just Uruk with Long Bows and miss 8 times. 32-8=24 points of damage . They ended up wasting 8 poisoned arrows against him as he saved every time.
For the Group 2 Uruks, 2 attack Ceol and 2 attack Leofwin. Ceol is hit by a Crit and nearly a second time but Felareth uses Cutting Words and the Orc misses. Ceol takes 13-8=5** . Leofwin is hit once for 7-8=+1 . These Uruks are skilled warriors striking twice each round.
Group 4 has charged down the path into Thoroncir’s group. 2 go for Gwaelur, 2 for Thoroncir and 2 for Bitur. Sadly those going for Thoroncir & Bitur actually invoke opportunity attacks against the Sentinel, Tunnel Fighter Gwaelur and he swings with advantage on all 4. The 2 on Gwaelur hit him twice for 17 more. He is down 41. He strikes 3 of the 4 trying to pass him. He uses 3 Menacing Strikes killing 1, and doing 28 & 29 to the others who are both frightened giving them disadvantage to hit. This group is devastated.
The frighten Uruks moss Thoroncir & Baygir. The unfrighten one would hit Bitur but deflects the attack and the Uruk misses.
Gilraen uses her Bonus action to heal Gwaelur 11. Down 30. Then she sings a song of Tinúviel her distant ancestor and sleeps the 5 injured Uruk of group 4 with points to spare. (Improved Sleep3rd).
