Pro mode hard server?

[ian26uk]

Ok so I did Treant with my 4*Shrapnel build and it went well so thought I would try pro mode Shadow Hound and was like mission impossible.
My 4/4 hound died in seconds one hit from the boss took me to 5% Hp and I have 12k so I guess a 10k hit.
Tried UB build thats 3* and surge build and the UB was about the same as Shrapnel, The boss must have over 2m HP.

The mods on the boss are Shattering impact 25% impact damage and Storming Boss does 30% more damage at half hp.

Someone offered to help me but as far as I know the HP goes up in a group and I was just seeing how hard it was on the hard server. I am well aware that one or two of my mods are not the best of the best but they are ok after all Treant was easy on Pro mode.

I would understand if I was not using the correct sets and mods and the weapons were not +10 and only one star but I am using the correct sets all +6 the weapon 4* +10 so is it just me that seems to find it far to hard solo or is it just a matter of get best of the best mod stats?

Shadowhound Pro mode is easy, just know his attack that's all. I ran him 4 times on Monday with the exact mutation (30% boss extra DMG was a bit of a surprise), keep your distance. When he does the swipe, rush or shadow underground then dodge sideway. His laser can be avoided with a Spring Leg or Double Jump. When he does the pull AoE this can be avoided by running opposite side. When he glows red kill the 4 blob thingy first, these pack a punch. Just time your shot on him to blow up his weakspot red orb, this will stagger him even when he's about to perform an attack. I solo him probably about 100 times in both season now. Key to this battle is distance and mobility.

My build is 4 stars Last Valour, Caged Helmet 3 Stars, 3 pieces Lone Wolf and 2 pieces Bastille. I usually kill him in less than 3 mins. Here's a screenshot of the set, it won't win any Youtube DPS competition but you don't need to, just avoid getting hit by the boss.
