Awesome, thanks for that insight, but! you put the Ironworks weapon on = have to beat T11 atleast to be able to get the tomestone needed to get it.
2nd best choice would be True Ice spear = lower Weapon damage.
But I have some good news (for me atleast) As Zeviand pointed out, drop CT and jump directly to FT combo after Dis on P2 which ended up doing much better. Manage to hit 300+ on both golem phases.
2nd thing was my insecureness on P4, which I have gotten a slight better hold on now. And with these things I managed to surpasse 300 and hit 308 with a total of 9 kills now. It's start and hopefully I can keep improving that number!
