Admittedly it is entirely possible I've missed something that was removed as a result of wearing the ring, but I've not noticed any differences in the game wearing the ring the entire time. In this EA the only thing the ring appears to do is remove the ability to use the tadpole super powers. Someone on Steam suggested it may help destroy the tadpole in the Edowin encounter but I can confirm it still takes multiple skill checks to actually destroy that tadpole using the dialogue options.
I'm eager to check the initial Omeluum encounter after each new patch to see if Larian changes the dialogue and tadpole growth levels to reflect those players to do everything they can to avoid furthering the ceremorphosis process. As it is there does not seem to be any reason NOT to take advantage of the tadpole's abilities in the first act since it reaches a specific growth level by the end of the act regardless of player activity.
