Sugary was practically relying on hit-and-back away tactics with the zombies(zombies, right?) while urging for Fantasy to move along with him. "See any more archers, raise the shield. Don't see any, raise it anyway. We need to hold out!" He simply could not leave Fantasy alone, but he also could not dive into battle with her too roughly, so he was forced to play more defensively. He did have one trick up his sleeve he could use well though: Since he could easily carry his shield with levitation, he figured he had one good way to attack well both near and far while keeping guarded.
Being adept in combat, he held his shield with his hoof, held the mace with levitation instead, and brought out one Steel Spear to wield with the other hoof to try and stab away at the zombies while keeping a tad more distance from them while doing so, and swinging the mace telekinetically towards any skeleton archers that happened to be near enough; Otherwise, he'd just bash and stab the zombies with both weapons while guarding with the shield.
