heres a few hints for you guys just starting
1: if the word medic is in there name, or if they start to heal or use a shield, kill them quick, they will be a major pain through the fight
2:high hits is good, criticals are better: if you can build your charater so he criticals alot, DO IT
3:not going down in one hit: keep your vitality high, especally when going with the darkness build, because again youll be smacking yourself with dark infuseion to get your focus back alot
4:keep to your element: dont just start buying everything, stick with eather electric or dark untill you beat the game/ get an *** kick build, as then it just dosent matter.
BARON tips: holy scars is your best bet for killing him, dont really hit him unless he has it, spend your time healing and buffing, youll need it, also, again, lots of crits are important.
MAYOR tips: TAKE OUT THE CANNON FIRST!!! if you dont, its going to be one hell of a fight, then just wither away at his hp untill he dies, MAKE SURE YOU HAVE FREE WILL AND SALVATION USE THEM AS MUTCH AS YOU CAN.
