All you need is a good strategy to beat the Baron... It might take you like 20 minutes in one battle but you will eventually kill him... also sometimes you might get him to cast tick tock on himself.
Sorry for double post but the enemies in zone 7 would definitely be a challenge for anyone who goes up against them... unless of course if you hack your stats like some people... The corruptor is easy to beat so one of the other guys in zone 7 would be hardest to beat (probably unless you count the fact that in other battles you are lower level therefore everything is harder according to that level)
Yeah, the Baron was kinda hard when I was lvl. 13, I thought I was gonna take up a whole day fighting him XD (but it actually took about 15 mins., WTH?!)
I was able to defeat the baron realy easy for some odd Reason :S one time i tried killing him he didnt use ticktock until after he did his holy wrath thing were you can PWN him with ur best skills :D
The hydra was pretty easy actually I actually was trying to get the pacifier achievment on heroic (I did) Have max crystalize and 3 max reforms max disrupt and I had some other defensive moves and set veradux on relentless and roald on tactical. I crystalized the hydra and then used disrupt and kept him inactive until veradux kills the 3 fire claws with electro bolt but then i forgot wat i did
