Theory:

This reminds me of the issue automatons used to face when using a scanner attachment. Robel-Akbel appears to favour casting spells of an element that the Umbril is weak to - generally Fire-based. Perhaps the Very Tough mobs are too strong for Robel-Akbel to be able to discern a relative weakness?

Using Conflag Strike would always be enough to force Robel-Akbel to always cast spells on Tough umbril, but never Very Tough umbril. The Burn effect of Conflag Strike reduces the INT of the umbril, rendering it more succeptible to magic attacks. This would appear to support the idea that Robel-Akbel is not casting spells because the umbril are "too resistant". Meteor Strike, a similarly-powered attack that does not inflict Burn, does not have the same effect.

Just an idea. Hope it helps.
