Crabatrons have higher health than Ichis, therefore, the advantage of Crabatrons over Ichis is that they can survive longer when attacking players or wild monster tribes.
They also deal higher amount of damage than Ichis.
But, it is more advisable to use Ichis plus Zafreeti in attacking wild monster tribes due to the fact that Ichis are less expensive than Crabatrons.
Ichis can take out the defenses of those wild monster tribes for your looters or your last wave monsters.
