From: qwertyman2002 | #005 Dex decreases cast time. If you want to make your cast uninterruptable, you need a Phen or Bloody Butterfly cards. There's some equipment that also does it, but it's easier to get a card.
wuts a phen? ANd what sorta equips outta I get?
Oooh...i never noticed firewall was that good. It's sexy~
phen card, goes in an accessory, makes your cast uninterruptible. it also makes your cast time longer. but you can get around this effect by hotkeying your phen, begin to cast and then immediately put your phen on. this gives you your normal cast time but you can still be hit without your cast stopping. :)
