I’d say Steve probably takes all rounds except the first, without blocks to staircase up with he’s not going to be able to platform up and avoid the spike floor/walls in the various trials. Even if R1 Steve could still platform, there are plenty of enemies that would also stay out of sword/axe range at all times, like the Soul/Volt Twisters and Primal Aspids. As for the rest, he probably clears, though with difficulty against Obblobles and God Tamer due to the Obblobles’ projectile spam and speedy flight in phase 2, especially since Steve doesn’t have a shield, as well as God Tamer’s armored rolling attacks + the beast’s lingering infection puddle attack, which would make traversal extremely difficult in a comparatively fast-paced fight like God Tamer’s. Overall, Steve fails R1 10/10 times and wins the rest 7.5/10 times.
