- "For seconds, you cannot be knocked down and you do not suffer extra damage from a critical attack."

The nearly 50% uptime of this skill made its usage not take much skill. The fact that lots of monks use this AFTER they got knocked down, and its still up for a spike a bit later is a little ridiculous. Changed the recharge to 20 seconds and nerfed the duration so it should be 4 seconds at 8 spec in Tactics. This promotes using the skill with intelligence and it won't be available on successive spikes (which usually are spaced by about 10-15 seconds).
