Remember in Symphony of the Night that was a little chance to get Alucard petrified as a Gargoyle?, I thought that was a cool idea seeing a similar effect in Bloodstained.. like seeing Miriam to get petrified as some Winged creature or something like that. And by the way, in SOTN, when this (rarely) occours, Alucard gets invulnerable to any damage, so it will make sense to do the same in Bloodstained.
