[The entire top of the platform is covered in soil, only the very edge near the stairs is clear. I'll say it's close enough to reach thornslinger2 but not 3]
Ke'Sha issues new orders and Alrius descends to retrieve his sword, while Nidrith continues to hack away at the new target. Alrius rejoins her at the top, both skirting the edge of the platform and avoiding the soil. The vines continue to whip and throw more thorns, one of which tangles Alrius’ foot; sending him crashing to the ground below! Even so, the outcome of the contest is clear as the juju zombies finish cutting down the second plant; impervious to its attacks.
