Phoenix has an AOF about 1,700,000 Joules. So a bit above that since that was the AIF of his attack.
If a cane scales to Manfreds durability. Than yes. It is stronger than Nathan. The amount of times he has been exploded doesn't matter. The force behind them does. His cane can tank hits from Phoenix's attacks. We can't look at this like "oh well this is just a normal cane" because it isn't. It's like saying "oh frisk is just a child, so even though his explosion feat put him at small building, he shouldn't be stronger or more durable.". Doesn't work like that. In this case, the Cane has taken stronger forces than Nathan has.
Cane can take blasts that hurt people of 1,700,000 Joules at least (considering his attack provided that force as an AOE. And the direct damage would be a good chunk higher)
Nathan has taken (I think it's around here), like 600,000 Joules.
So the cane in this case would clearly be stronger and harder to break or damage.
She hasn't had a reason to though. Even if she was beaten, she doesn't play fair. She literally tricked a man into killing himself. It wasn't like her being mad she lost. She downright wasn't ready to leave. She just was forced out. Again. It doesn't make sense that she would leave. If she had control over Maya's body, she very easily could have gotten thee revenge she wanted. She already saw just the thought of Maya's death or being held against her will really upset Phoenix. It put him in a bad place. So why would she leave her body then? She could have easily just refused to leave or used the possession and say, kill maya. Like she tried to earlier in the case. Her only goal was revenge. She didn't care how illegal it was or who knew. She admitted to her crimes during the case cause she simply didn't care. She was dead. They couldn't do anything to her really. And all she wanted was to get revenge on Mia and Phoenix. So killing the one that matters most to both of them or just not leaving her body holding her hostage is really gonna hurt them. But the fact Phoenix said he didn't care about the case and he at that point only wanted to get her or of Maya's body then does the typical thing he does when using his powers. And she's forced away. Even making quick clear screams that she wasn't ready. And I brought up the other stuff because while on its own, yes it doesn't give him that ability, but it supports the fact he would have that kind of ability on with the fact we see it happen. So it isn't he just possibly did it once. It's He has shown several times to have powers supernatural to others that regard seeing, feeling, and interacting with spirits. Even possibly summoning them himself. The other stuff was brought there to have a little more comfort that his abilties reside in that kind of power and abilties
Like. Let's say we see Sans do the same thing as Phoenix.
Vs
We see Mr Bean do the same thing as Phoenix
Obviously. Since we see sans work with soul stuff so much, it's far more believable that his would be legit next to Mr. Bean who has 0 connection to those kinds of powers.
Phoenix in this case just shows a lot of connection to spirits and connection to them. So it isn't exactly far fetched that he can do that considering what we see and know. That's why I brought it up. Not as the basis for my argument. But just as some small reinforment
