I'm not saying this is the best team, but I playtested the Monk in the Trial using random hero draws, sticking Kubo (Monk) with Link (Elf), Penny (Dwarf), and Drew (Druid). None of these guys really stick out as a tank (Maybe the Dwarf) but they had a decent and complimentary showing. Link chose Time spells (Flashback, Slow and Time Stop), Drew had standard Druid spells and now we'll see what the Monk is capable of in a group quest.
The first room Link found no traps, ran out the door, to the corner glimpsing the 2 corridors.
Penny tried for treasure but got a Hazard.
Kubo ran out into the hallway and spoke to stone, finding nothing.
Drew only rolled 3 so lagged behind.
Link rolled high enough to reach the alchemist room and managed to take out one of the orcs.
Kubo, Penny and Drew and rolled too short to reach the other orc, but Kubo at least made it into the room and Drew cast Shapeshift on herself. He was attacked by the remaining orc and used Twisting Torrent to avoid 1BP of damage.
Link's attack was blocked, Penny failed to reach the Orc but Kubo took him out using Eye of the Storm and running into the weapons rack room, leaving Drew to search for traps.
Penny was standing in the doorway and attacked by the Abomination, taking 1 damage, down to 5BP. The Goblin went after Kubo, despite getting 2

s the Monk blacked it, therefore unable to use Twisting Torrent.
Link found 25 gold since he had no way of getting into the weapons rack room.
Penny rolled

on her attack.
Kubo currently in the room used Strength of a Mountain to attack the Abomination, taking it out. Drew ran in after, finishing off the Goblin.
Link searched for traps.
Penny searched for Secret Doors.
Kubo found the weapons rack to have only chipped and rusted weapons.
The heroes ventured out to the room with the Dread Warriors. The Elf lagged behind so the Dwarf was the first in, attacking a Dread Warrior and managing 1 hit. Kubo followed him in using Eye of the Storm to attack both Dread Warriors, one blocked the other took 1 damage, both Dread Warriors down to 2BP. Drew ran in to attack the 2nd one but was blocked away.
The first Dread Warrior brought the Dwarf down to 3BP. The 2nd one attacked Kubo, who blocked it.
Link arrives and lands another BP of damage on the first Dread Warrior. Penny's strike was blocked. Kubo danced around the room with Tidal Surge, and was able to land a hit. Drew flopped on her attack.
Penny blacked the Dread Warrior's

attack, Drew took 1 damage, losing Shapeshift.
Link rolled

and took out the first Dread Warrior, leaving Penny to land a final hit on the other Dread Warrior.
Kubo followed up with Speak to Stone and Drew cast life force of Penny, bringing her back to full health.
Link discovered that the chest was empty. Penny and Kubo allowed Drew to search the room for treasure, but it was a Hazard, she lost 1 more BP.
As the heroes made their way to the middle room Drew cast Pixie on herself and brought herself back to full health, reclaiming Shapeshift.
Preparing for the battle in the middle room Link cast Time Stop on Kubo. Penny ran in against the Orc, but flopped on her attack. Kubo used Strength of Mountain to attack the Dread Warrior and managed to drop him down to 1BP. Using his 2nd turn from Time Stop Kubo followed up with Eye of the Storm rolling another

, which dropped the Dread Warrior to 0BP.
Drew ran in to attack the Orc in the rear, successfully.
Instead of attacking the Dwarf the Orc charged Kubo, who blocked his attack. But Verag went after Penny, landing 1 BP of damage.
Link ran in and took out the Orc fighting Kubo.
Penny failed to hit Verag and ran away to avoid further attack.
Kubo activated Tidal Surge, charging Verag, attacking and backing away, landing 1 hit in the process.
Drew gave it a shot, but flopped on her attack, leaving Verag to attack her.
Despite rolling 2

s in his attack, Drew managed to block with

.
Link ran next to the Gargoyle and rolled

in his attack but Verag blocked both!
Penny couldn't get close enough to launch an attack, but Kubo has already exhausted his Earth, Air and Water techniques. He couldn't get past Drew to make an attack, so blasted right through her with Burning Spirit, destroying Verag.
Drew searched for traps.
Link searched for Secret Doors
Penny got the chest for 120 gold.
Kubo's search of the room brought in a Wandering Monster that did no damage, and Drew attacked but it was blocked.
The Orc proceeded to attack Link and landed 1 BP of damage, but Penny took it out on his next turn.
The group circled around the central chamber into a room with 2 Goblins. Kubo was the first to enter and attack, but he flopped with Eye of the Storm, only attacking one, forgetting that diagonal attacks were enabled.
Drew followed him in and took out one goblin.
The other Goblin
did manage 1BP of damage but Kobu avoided damage with Twisting Torrent.
Link ran in to finish off the Goblin.
Penny was lagging and still hadn't made it to the room.
Kubo used Speak to Stone, clearing the room... But he must've missed something as Drew got a Hazard. But that would break her Shapeshift ability, so Link cast Flashback, undoing that search.
In the next room with the Sorcerer's Table Link took out the Orc, Penny flopped attacking the Goblin but Kubo finished it off.
Drew searched for traps.
Link looked for Secret Doors.
Penny found 15 Gold.
In the next room with 2 Skeletons, Link took out the first one; Penny's attack was blocked; Kubo used Tidal Surge to move in, attack the skeleton, which he failed to land a hit, and move to the door, opening it; Drew rolled short.
The Guardian Mummy rolled 2

s, but Kubo blocked the attack.
The Skeleton attacked Penny, taking her down to 5BP.
Link had to finish the skeleton off on his turn.
Penny couldn't really make it the next room as Kubo and the guardian mummy were hogging the doorway.
Kubo used Strength of Mountain getting

, but the Mummy blocked 1.
Kubo moved and Drew took his place, managing to hit the guardian with a 2nd

.
A Zombie then attacked Drew, dealing 1 Damage as she lost her Shapeshift.
Link and Penny still had no way of getting into that room so they satisfied themselves with Trap and Secret Door searches. Kubo, however, used Eye of the Storm to attack diagonally through the door, but he still missed the Zombie.
Drew managed to take out the Zombie with her dagger and ran in the room so the other heroes can get in. But the Zombie blocked the doorway again and attacked Drew, but it flopped on the attack.
Link ran to the doorway and failed on his attack.
Penny couldn't make it in so searched for treasure revealing a Potion of Healing.
But Kubo has exhausted the 3 styles and could now blast the last Zombie out of the doorway with burning spirit.
Link and Penny followed in with trap and secret door searches. Kubo found a Mysterious Flower on his treasure search. Drew waited by the entrance of Fellmarg's Tomb for the next round to start.
Link ran in and took out the skeleton adjacent to the Mummy. Penny followed her in and attacked the Mummy, surprisingly rolling

, which took out the Mummy. Kubo attacked the other skeleton diagonally through the door with Eye of the Storm, taking out the last monster.
Drew ran in looking for traps.
Link searched the chest.
Penny searched for Secret Doors.
Kubo searched the room for Treasure, finding another Potion of Healing.
The heroes circled back around to the torture rack room where Penny killed the Goblin and Kubo took out the Orc.
Drew's treasure search resulted in a Treasure Hoard of 300 Gold!
This worked out well as some of the heroes really worked well together, like the Elf using his time spells to assist the Druid and Monk.
I guess the Dwarf was the only one that seemed out of place as the 1 thing that makes him special, trap disarm, wasn't used.
Normally I feel the Dwarf could be a great asset with that ability as he doesn't only remove a trap from his path, but from his allies' as well. It makes him a needed member of the team, so much so he might be one of the best heroes to have on a team. But in this quest she felt like the odd man out as nothing distinguished her from the rest of the heroes.
The Monk surprised me, I didn't realize how frequently he'd end being able to use Twisting Torrent. I realized with the monk sometimes you need to open doors prematurely to build up to that Fire technique. I also saw at times when you think you're regaining the techniques a Wandering Monster might appear between your turns and you can use... Interesting.
I also felt the Druid was really helpful, maintaining 6BP for Shapeshift and healing other injured heroes.
