Tip: Crystal Guardian – Let Maria/Anne do the rush. ALONE!

Crystal Guardian BOSS has sky high defence. the only real way to damage him is by critical hit.

There are only a few characters currently with buff that raise the party critical hit rate.

1. Maria – After rush: Critical Rate +40% (party / 20sec)
2. Anne – Passive: Critical Rate +30% (party) / After rush: Critical Rate +60% (party / 20sec)
3. Nel – Passive: Critical Rate +10% (party)

Also, there is a yellow triangle icon beside the character portrait when critical hit rate buff is active. Use your best attacks when you see the triangle.

Don’t bother rushing if there is no critical hit buff unless you are Maria or Anne.
