its about the enchanting system in skyrim. ive got a char which i played long long time and when i became lvl 57 today i could finally add that talent in enchanting "extra effect" .
now theres my question: when i enchanted my dragon armor before getting to skill 100 in enchanting i could drink that enchanters potion and put up my health boost on the chest armor up to 84 health.
now i got the extra effect option and suddenly i can just go up to 70 hp for the first enchantment.
is this some kind of bug that just happens at my game or is it normal that 2 enchantments on 1 item are each less effective than having 1 enchantment which is slightly better?
hope to get some help here. i lack english so i hope everyone reading this understands what my problem actually is.

nono. im much more reasonable.
