I would have applied for one extra slot but the way the tourney is now means I will never get into games outside of weekend. not like that already happens to me every workday :V
The way I understand it, magic immunity just means people can't use single-target effects that they need to click on you for. (There aren't a lot of these in DotS)
Green Dam nullifies Cirno's proc damage, but the slow still stays, as Pesco says. It does this for many spells, though there are exceptions that pierce the Green Dam shield.
Also I'm out from the tournament/league w/e, I highly dislike how its structured and everything.
But we WERE gonna lose, until I turned 1% into 100% with HOT BLOOD and BURNING COURAGE. (and some shittalking to keep myself motivated and entertained)
