I have found a bug! If you find an area with a chest, pick up loot from it, kill all mobs in area. After this get other area and then return to area with chest. You'll find out that the chest is closed and there no mobs. You can do this for hours :DD
I hope, that this comment will help all of you to make hard without titles.
You have to begin with Celestial Lightwielder. Use Sanctuary every time if you see danger, it doesn't heal enemies, so don't afraid to use it when they made a circle around you.
Every lvlup you have to do 1 point in strength (because after you find weapon with critical you will always oneshot everything with crits, 3.3x multiplier), 1 point in stamina (because without this stat you won't be able to take damage from different sources even with heal) and 2 points in willpower (the more willpower, the more Sanctuary at once you'll be able to cast). You don't need intellect points: increasing only magic damage done by spells (after 12 lvl spell damage is no match to melee damage, especially with crits).
It's important to collect ICE and FIRE resistant equipment, because there hords of monsters wich do fire and ice damage (I got killed on lvl 17 because 3 ice mobs get fast kill with me, I have no chance to survive).
In this game there is a very strong bug. If you open inventory and choose any equip from any of your heroes and after that make a click on options (yellow button) and then close the window. You will lose your equip, but the stats won't get lower. Using this bag for half an hour you can made your Veradux to make 50k damage per shot... + all to see.
P.S. If you do re-spec all the bug stats will reset to normal stats.
Baldhitman, The Secret to kill this boss - making his focus me on 0. Then he restores focus and looses hp. With biological you can do such a thing every time, because it's disruption can be on the panel for 4 times.
