The Kekkaishi is the 23rd job in Minute Frontier.
Overview
The Kekkaishi is female, wearing a white kimono that is red from the waist down and has purple highlights on each arm. He black hair is tied back by a purple hair band to form a long ponytail. She is unlocked by defeating Salamander and progressing to 11.9km.
Strategy
The Kekkaishi is the magical counterpart to the Geomancer, focusing on defense over magical output. Instead of VIT however, MEN is used in mass.
The stats are rather extreme, gaining 5 points per LVL of MEN, allowing for immense magic damage absorption that most magical jobs miss out on. The stats can also be used to supplement MEN to other builds, making her a viable option in most playthroughs.
Abilities and bonus highly suggest Staff play, allowing for intense magic attacks.
A key ability of the Kekkaishi is Magic Barrier, allowing for magic resistance while the player does not tap the screen. This allows for intense magic tanking on its own, even more so when paired with the fantastic MEN gains. Of course, the weapon that requires the least amount of input to attack at full capacity is the Staff, allowing for ridiculous synergy with it as a main weapon.
