Sure! I'll leave that boon behind for now, then, I like his fog form itself how it is. I'm assuming you mean he'll keep both and this one just won't get to be demonstrably more powerful-- presumably because if he can do it outside of fog days that's a lot of Stronk without a lot of checks and balances.

Would it still be permissible to have him feel more territorial and have a somewhat shorter temper in this form, without any tangible physical increase in power, or would you prefer the changes be purely physical and not psychological?
