Eliphas did not pick up the "alms" of the Black Swordsman, but instead condensed a magic thrusting sword with high temperature and electric current through magic power.
Even after enduring the dual blows of the Overlord and the Dawn Dragon, he maintained his composure during the battle. Upon seeing the Black Swordsman's heavy armor, he immediately came up with a strategy to use high temperature and electric shocks.
As for why he chose a thrusting sword, it's his personal habit. Though the difference between a greatsword and a thrusting sword seems vast, with Eliphas's combat skill, he wouldn't be at a disadvantage.
As someone who climbed up from the bottom, his martial skill far exceeded his magical prowess. Magic alone couldn't intimidate mercenaries!
The Black Swordsman held the great sword with both hands, facing off against Eliphas from afar.
"Captain, let's help too!"
