Projectile-based combat was perfect for space abilities since it could disappear through the folds of space in front of the caster and then appear behind the target to stab them from unpredictable angles.
But no one said using close combat weapons with space was any less effective. One could cut through space with a sword, creating void slashes akin to sword lights, or use spears and even halberds.
And when taking wood and darkness into effect...
Look, if Dalvin wanted range and the ability to strike a foe by limiting their dodging and evasive ability due to proximity, his best middle ground was a long weapon like the spear. However, even within this category, there were many denominations like hammers, halberds, naginatas, tridents, glaives, guandaos, and even pikes.
