Mace fightning.
Take it from someone who can solo Dread/Parox/Shimmer/Grizzle... etc.
Quarter Staffs for the 1v1 (Double strike spam... You hit twice, thus doing twice the damage. Depending on what you're fightning you can chain this non stop, or rotate w/ lightning strike 2:1 or 3:1)
Black Staff for 1vWhatever (Whirlwind)... Does MORE damage than radiant. Throw 4 mods on & enhance w/ 10%ssi unless you're amazing stamina (My wammy/sampires have all 5hp, 8stam, 2mr, 8lmc suits). The extra DI is worthless from yew because you SHOULD be max w/o it. As a wammy soul seeker is poop imo (get mad!). The only useful mods is mana/stamina leech... Life leech is pointless w/ curse weapon. Repond slayer is pointless because of talismans. (You should have undead tally, vermin slayer tally, owned by noone flame/ice/etc... and a variety of protection/killer talismans for certain situations). Shouldn't rely on DI from talisman.
It's straight STUPID how fast I can kill DF now. I use a tetsubo (I think... The wpn exiler is... spiked club thingy) w/ mana/stamina/demon/ssi/di & qstaff w/ mana/stamina/demon/hla/di. My script swaps weapons if I'm full life, hits with the frenzy whirlwind, swaps back to my qstaff and spams doublestrike/ls (after it curse weapons) until the frenzy whirlwind timer is up and repeats.
I've actually been working on my doom script to make it a little more automated. I can AFK anything in there thanks to imbuing & new crazy weapons you can make. I run a wammy & 4/6 chiv 120 eval 69.9 magery SDI s/w discorder as my 'companion'. For DF all the script does on the discorder is discords (duh) and holds a remove curse target up for when wammy gets blood oathed. When df hits a low percentage of life I WOD till he dies & get looting rights & 'doom points' on both chars for doing enough damage.
