Can you make it through the dlc with this?
Working on making my way up to Mohg right now with this type of build
I don't think you'll have much of a problem but you may want to upgrade a crossbow or something for a ranged option
The builds that have the most problems in my experience being summoned for co-op tend to either be int casters who don't know how to dodge or people who decided to use the blasphemous blade because a youtuber told them it was broken last month and they didn't see that it got nerfed
If you enjoy those, great, keep at it.
But they don't really compare to the insanity that is Blasphemous Blade + Dread Talisman + Fire Scorpion + Alexander's Shard.
I used the Ruins Greatsword the whole playthrough (swapping out for a new DLC one for the final boss) and had no problem (except for the final boss), though it must be noted that I am a scrub and summoned Mimic Tear for every fight.
Doing jump attacks with double strength weapons does so much damage that it kinda works on anything if you can take a hit or two, even in the DLC. Just make sure to explore a lot and find the little tree fragments that make you tanky
After beating it with a two caster builds (pure Int and Dex/Faith) I'm partway through a pure strength run and it's a lot tougher due how much more mobile and aggressive a lot of the bosses are.
I used bloodhound fang for my whole playthrough. Base game I somehow managed to do solo except for Placidusax whose kamikaze attack I could never see coming so I summoned Latenna and hoped that he would crash on her.
Using the same build in the DLC but main bosses are very difficult. I am using Latenna +10 throughout and right now I am stuck on the last story boss. I also need to get more scadu blessings. I am on +10 right now.
