Updated for breaking changes in RMT 1.2
Added some colours, made major balance changes, and fixed a bug.
The risk/reward skew of parry was too crazy, so I've toned down how powerful the followup attack is. In exchange the parry window is much longer, making it much easier to get stacks. Since stacks are easier to get, I've reduced the buff duration from 30 to 20 seconds too. Finally, I've added an alternate parry that retains the tight timing for higher damage - although it still doesn't restore the damage reflection from before as that was simply too powerful.
