[b38] Repulsion Blast hits twice

[donkatsu]

I noticed in the changelog that mindslayer knockback abilities hitting twice was considered a bug, and has been fixed. Well, the paradox mage talent Repulsion Blast also hits twice sometimes, so I'm guessing this is a bug too? I just never reported this because I thought it was a feature; the Gravity tree is a little weak otherwise.

This was an accidental feature (I've been aware it can hit twice for a long time and have kept the base damage in line to compensate).

But I'll fix the talent description to account for it.

*double kinetic spikes were hitting for 1k without critting with a level 5 test character and there's plans to make the AI smart enough to use aura spikes, hence the changes in the SVN*
