yes it can still be done. You need to re-equip your gear after popping the potion or the new stronger effects don't apply properly.
In before people [censored]ing about exploitting
Thanks for confirming. As I said I only want a powerful bow capable of oneshotting, as I plan to try and pull off head/heart shots on an entire dungeon, and it only makes sence they die straight away

also it would be good to test how far enchants could help (Like to see if enchanting sneak by 10,000 actually makes a difference from 100 sneak)
(and in my opinion, I'm suprised how all those crying over exploits aren't also crying over PC console commands, as that can be used to exploit further! but not to detract...)
