Uhm.. actually you dont bolt ._. you get 99 dex and with magic strings you storm gust cause the boss takes all 10 hits and by that time you can cast another storm gust. And with other attackers you can hitlock it providing it doesn't use earthquake.
Wow! You would have to be a level 99 Wizard or at least a High Wizard to get 99 INT AND DEX!
There are plenty of problems that could happen in addition to the Earthquake skill.
Problems that could arise include long range attacks. A Cecil Damon could kill you long before you got within range to even begin casting storm gust. Then there are the cloaked mobs like Eremes Guile; what do you do when you can't even SEE your target much less cast a spell on it?
A good example of a boss that would pose a problem even with INSTANT Level 10 Storm Gust would be Ktullanux. What would you do with that boss?
