Lighning dragonsteel swords are usless against Lighning Dragons

[MasterUsername11]

The lighning dragonsteel sword upon impact spawns a ligningbolt that heals lightning dragons in combat. That healing is bigger than the damage caused by the fire, so in hunting for more lighning dragonblood you can't use that sword. Ice and Fire Dragons doesn´t have that problem an both can be killed wich their corresponding dragonsteel swords.
