['Slave Mark' (Rank 5, Level 1) has been drawn!]
"This is the best ability we could've gotten, Lord of Shadows!"
I nodded, keeping my expression calm even as my thoughts moved quickly.
'This is good.'
Rank 5.
That changed everything.
'It will work on Rank 5 Exorcists too.'
Slave Mark wasn't a single fixed skill. It existed in tiers. Its rank determined the maximum level of Exorcist it could be used on. Lower ranks were useful but limited. Rank 5 meant it could be used on Rank 5 Exorcists.
Once the mark was placed, the target had to follow every order. They couldn't harm the one who marked them, either directly or indirectly. There were no loopholes there.
The condition, however, was the real obstacle.
To activate Slave Mark, the target had to agree to take it.
That single requirement made the ability difficult to use in normal circumstances. Most people would never consent to something that stripped them of their free will.
