How to Beat Ruin Kobold King Guide

[1] Don't Get Caught Off Guard by its Magic.

BossAttack1

The boss fight consists of three phases. In the first phase, the Ruin Kobold King uses ice and fire magic to bombard its targets. Stay alert and avoid the elemental projectiles.

BossAttack2

During the second phase, it can fire a barrage of homing energy projectiles that inflict Instant Death.

[2] Misery Loves Company.

BossAttack3

Don't let the Ruin Kobold King's goons pile up. Use your Weapon and Combination Skills to clear the field and get your focus back on the boss.

[3] Brace Yourself for the Ultimate Impact.

BossAttack4

In the final phase, the boss ditches its weapons and decides fists are the way to go. Oh, it also magically enlarges itself to make things more interesting.

The Ruin Kobold King shares several attacks with previous Shrewmen bosses, such as the Shrewman Queen, so those guides may help you prepare.

BossAttack5

Watch out for its signature move, where it leaps into the air, charges energy into its fist, and slams the ground to trigger a series of explosions. Each blast is larger than the last, so dodge according to your distance from the impact point.
