Treants are typically chaotic good entities who come into their own sentience as the result of cultivated potential and druidic care over time. Saundor’s corruption of the Shademirk was further demonstrated by the hatred infused into them, both visually by means of his tar and mechanically through their blind, unquestioning assault on whoever was closest.
Though initially awakened by Saundor, the treants acted of their own, hate-driven volition throughout the battle. They hit whatever was closest by, which was almost always Percy (sorry, Percy). One got an attack against Vax’ildan, but was dead by the time its next turn came around. That same treant later landed an attack on Vex’ahlia, but that was due to her running from it, provoking an attack of opportunity. Keyleth might have been a good target, had she not been living flame and within the treants themselves. Saundor wasn’t afraid of hurting the treants, either, as evidenced during his casting of Reverse Gravity.
Vox Machina’s Strategy
Vox Machina also played to the best of their ability, for the most part of the battle. Here’s a rough outline of their strategy, provided by L and N:
“Run in with a plan to woo, realize he is the world’s biggest asshole, stab and burn him to death as quickly as possible while scrambling to avoid arrows, spells, and lair actions.” “Boom, Vestige.”
Vex became the focal point of the battle, and accidentally played meat shield to the corrupted’s wrath. Both potions she used proved effective in wasting Saundor’s attacks, giving her enough hit points to force him to use another arrow in round 2 and just barely render his second Blight unable to put her down.
Keyleth’s decision to go Fire Elemental paid off very well in several ways. First, the treants’ vulnerability to fire ensured that she was the primary controller of the minions in this battle. Second, even without Tree Stride, she could occupy the space of the treants. This not only dealt extra damage at the start of their turns (that was also doubled), but also prevented her from becoming a potential target from the other treant in play or Saundor’s assault. Third, even when she did take falling damage from Reverse Gravity and Scanlan’s failed toss, her fire form resisted the damage.
Vax got the first hit of the fight on Saundor (after Vex’s surprise round), then spent most of the battle helping Keyleth take out the treant complications from the battle before sprouting wings to confront Saundor at the end. Percy got a few hits on Saundor (resisted due to nonmagical ammunition), and helped Vax and Keyleth finish off the second treant.
Scanlan provided excellent support, in spite of being tied against the wall. His first Counterspell prevented Saundor’s Wall of Thorns rendering the terrain very difficult to navigate, and his Healing Words brought Vex back in the fight and kept Percy in it. Although both castings of 5th level fireball were resisted, every little bit of damage on the big guy brought Saundor closer to death.
Even Grog, who “didn’t do anything” and was “running around like an idiot the entire game,” managed to deal damage to Saundor almost every round. Grog also spent a bonus action to summon Ukurat in the middle of the second round. Although the werewolf didn’t appear until the third round and couldn’t contribute in the final round, his appearance provided a morale boost to the party and an attack of opportunity to the antagonist.
