Tobias realize that Ghost managed to resist the magic and only took half damage. Tinkara feel that thunder damage is just as ineffective. And ghost is till standing, though you can see visible holes in it's matter which is not as thick as the other 3.
OOC:
I'll ty to understand how to address your movement now as I've fixed Criella's position
1. In order to avoid 3rd attack of opportunity Tobias will move this assuming Criella moves to make it not difficult to move through here location
2. Nyx could get here a but futher down the corridor.
3. Frog has only 20 feet of movement and I will assume it does dash action instead of hide as there are nothing to hide behind in the corridor
Let me know if my interpretation of your actions are good or not, meanwhile rolling attack of opportunity
Both ghost creatures manage to make their deadly hugs with Tobias as he retreat further reducing his will to live
OOC:
Two more con saves from Tobial please. And sorry - forgot to tell you that you failed first save so your max HP is reduced by 20, i.e. if you have 34 out of 73 max you instead have 34 out of 53 max and healing magic will not get you above 53.
