I just unlocked the Master class spells. They are practically worthless. Master Frost is kinda cute but deals pitiful damage. Master Lightning is the only usable of the bunch, as a dragon killing tool because as far as I could see, it's the biggest range hitscan spell allowing you to more easily kill a dragon that stays far. Then the fire spell is utter crap.
Master spells are unusable in real fight situations because you get staggered by practically any hit before you cast it. Worse, they are forced dual wield spells that seemingly do not benefit from dual wield perks. I get less DPS output out of the master lighting spell than spaming the dual cast expert one.
The tunning on the spells is just plain broken, you can see it easily with the master spells. Exemple : Fire
- Fire Master spell costs 1200 magicka (before perks and the like), takes 5s to cast while you are stuck in place and most hits will interrupt cast, then does a 100 damage centered on you and it uses both hands always
- Fireball Adept spell costs 114 magicka, nearly instant cast, you can move while casting and before releasing it and and it throw two at once.
Let's assume you use the dual cast perk and throw a dual cast Fireball. The two spells merged ends up costing 40% more magicka for a total of 320 and the damage is 10% more than two fireballs for a total of 88.
The Adept fireball spell does 10% less damage than the Master spell and for that it gets those benefits :
- nearly instant cast instead of 5s
- no risk of cast interrupt
- can move while casting and with the spell charged
- does more damage to targets on fire (Firestorm doesn't mention that part)
- can stagger opponent with Impact perk
- is an AoE at a range and not centered on a squishy caster that gets interrupted easily
- costs 75% less magicka per cast
Who at Bethesda did the Destruction magic tunning exactly? Because he must have been high on some illegal substances when he entered the numbers.
So as a tip for mages : don't use the Destruction master spells at all. Well if you got 0% spell cost, have fun using the master lightning spell to snipe people and dragons very far away. At least it works for something
