Currently whenever a new player dares to make the decision to upgrade the base armor set the game progression provides, experienced players give them a concerned look, as there is no real benefit to using cobalt. Ideally Cobalt should provide a reliable, defensive benefit that helps new players get comfortable with the game, and is useful on any mission or floor. Solid normal and piercing defense stats alone generally don't suffice.

Change: All armor/helmet pieces from the cobalt line, including Almirian Crusader, come with the stat +1 emergency revive.
Wearing the complete set gives the player 3 emergency revives per floor.

Effect - switching off of Cobalt comes with a tangible downside. Though as sparks become abundant in player's inventory and the player gets familiar with enemy attack patterns, the player should feel comfortable to eventually switch from having +1 emergency revive for more useful stats.

Because dying is the most explicit form of negative feedback, it's also very easy for a player to tell when Cobalt no longer is useful to them.
