[Snake]

Well, my idea for Spellthief's Smoke Screen's 'revamp' is:

--Instead of a 'smoke wall', the shape's a 3 to 5 squares long 'circle' full of smoke, which creates a zone of smoke tiles that makes everyone inside lose HIT by (Rank*10) and gain Evade by (Rank*10).

Ways to counter it (not mandatory, just changing to what I suggested above is fine enough.):
--Since smoke is so 'fragile and uncertain', any AoE spells that change terrain will make the smoke tiles vanish. So Sanctuary, MG's Celsius shell, Verglas's Fox Discipline skills, Mage's ice/wind spells, Hexer's Black Bubble, Youkai's 'jet'streams, Hyattr's charged firebreath.
