Vanhishikha Blocked the insignificant arrow with a quick obsidian glass shield before it melted into lava again. She fired off two dozen shards at the immortal as well as twice as many lava globs meant to explode near him. The shards should distract him if not impale and disable him then the lava globs would melt away his avatar. Vani followed close behind her attack ready to slash the immortal to bits with magma claws. Contingency plans weren't her priority but of he attempted to attack her with the same attack from before she'll just erect a glass barrier and discard it.
