As posted, you can see how strong the potion is. With 100 skill and all relevant perks (with no fortify alchemy gear) the 'Fortify Magicka' effect maxes out at +750 magicka for 10 seconds; with Alchemy gear my potions give me over +1500 Magicka which allows me to use any spell in the game without investing a single level into Magicka. It only lasts for 10 seconds but that is enough time to reliably cast two master spells before it runs out.
Dragonhide breaks down as follows:
- 837 Magicka base cost
- 494 Magicka @ 100 skill (-41% cost)
- 247 Magicka with Master perk
- 692 Magicka dual-casted (yes you can!)
I drink a 'Fortify Alteration' potion (base increase is +60% duration, 123% with the Fortify gear I use) then I drink the fortify magicka potion before Dual-casting Dragonhide. Dual-casted with Stability perk and potion my Dragonhide lasts for ~220 seconds (almost 4 minutes). I only use this combo for tough fights that I know Ebonyflesh won't cut it for.
