My cure 5 does 1020 and cure 3 does 290. Together that's 1310.
And hate seems to be less than cure 4. Went with some friends for a nyzul run and tested hate on Khim. I plan to test more when I can.
Spammed cures to get hate and have Khim run at me. The WAR voking it once and getting hate back. 2 minutes later, the WAR had body boost, let himself get into orange HP and used fanatics. Didn't get full cure VI, but more than my natural cure V; healed him for 1213. Then a minute later healed him with cure IV and pulled hate again.
