Danzel determination to turn his [Long Sword of the Sand Emperors Blade] into a truly cursed blade was pretty high.
The potential that the skill [Siphoning Soul Blade] had was enormous as it could infinitely make the skill stronger even if he didn´t upgrade it at all.
"Such a powerful skill is only on its 3rd-tier? I can´t even imagine how the skill will turn out after reaching the max level." Danzel though.
`I wonder how much each upgrade costs...´ Danzel thought before opening the cost of [Siphoning Soul Blade] upgrade.
[Siphoning Soul Blade]: Cost 700 000 XP (+50 000 per level)
"..."
Seeing the cost of the skill, if Danzel had a heart, by now he would be experiencing a heart attack. Most of the 3rd-tier skills generally cost around 350 000 to 500 000 XP in total. But this skill reached a total of 700 000 XP! The only other skill that cost so much was [Soul of Death Essence]
