Wait hold on, so it mutated from water or it is a rare mutation from acid or even mud ? ( i mean you said it a god mutation so maybe it the second one ? )
Is the slime acidic ? How much ? Like acid or more or less ?
Does it have any negative effect ( if it a rare mutation )
In what cirumstances did he mutated his slime magic ?
That was the AA lore. Magics had really nutty gimmicks planned for their mutations. Fucking Speed and Flash Magic were planned.
By now, with the consolidation we’ve seen (such as most magics not having DoTs/having them removed compared to AA variants) Phoenix Magic will likely just be a special fire with different tricks up its sleeve. Hell, we may get the wings with it to boost jumps and shit
