The Gardner is the 29th job of Minute Frontier.
The Gardner is gender ambiguous, wearing a full set of light grey armor with two white horns on both sided of the head. It holds a shield in its non-dominant hand. The job is unlocked by defeating Guardian and progressing to 17.5km.
The Gardner is a very specialized class, granting massive VIT gains per LVL along with HP and POW as well.
The Spear also gets some attention, gaining a sizeable 15% base damage boost as well as several ability boosts.
Abilities in general are physical defense related, having several Physical Guard Ups and the Guarder's key ability: Physical Barrier.
Physical Barrier is a rather tricky ability to use, conflicting with all of weapons except for the Bow, since the only input that would disrupt the barrier would be when shooting, which is far less frequent in attack interval than the rest of the weapons.
