Highest flat attack damage

What´s the highest flat attack damage in game? One handed and two handed

Look lige energy blade is 1 (one handed and two)

Replica alberon 2 (one handed)

Elemental hit 3 (one handed)

Echoforge maybe?

Theorycrafting onde a double repeat (Fatal flourish + echoing shrine) Vaal Volcanic Fissure on infinite leech Slayer or 99% block Gladiator. Both lack some high base damage weapon, Gladiator a lot more. Echoforge is sword and cant use that skill. Is viable to build a energy blade on gladiator?



Off topic: Don't seem much smart for all those zenith to put the best flat one handed damage in a two handed skill with lot's of downsides, much smarter doing it on regular molten strike like all valdo farmers.

my english arent good so idk if i understood ur point, but i want to try some suggestions... maybe im dumb (so i dont understand ur question, but maybe i can help a few, idk...)

rebuke of the vaal, hyaon's fury, essentia sanguis (if using 2 one hands, more flat than echoforge...)

rakiata's dance, Wing of the Wyvern, voltaxic rift, Debeon's Dirge, Wings of Entropy (near echoforge flat...)...
