No — Cobalt is a pure multiplier ore. Among non-trait filler ores in its pool it ranks #32 of 57 by multiplier, so it earns crucible slots on raw 1.5x power alone.
Ancient Boulder (Forgotten Kingdom) at 23.9%; Crystal Vein (Forgotten Kingdom) at 14.0%.
Cobalt is early-game filler: 1.5x multiplier is low, so swap it out once better ores from Forgotten Kingdom or beyond are unlocked.
