He put the link on an existing “Holy Artifact of Tiernon” that was the key (shhhhhh don’t tell anyone). It’s what allowed him to penetrate the mana stream, in a manner similar to how those arrows could affect Talarius’ armor.
Pretty sure Sir T would object to calling him and his friends mana sucking vampires. Talarius knows about vampires…ahh Melisance…boo hoo already so you lost someone sheesh, what a windbag…
the energy blasts vs Lenamare were pure spirit blasts on the astral plane. Lenamare’s wardings and spells brunted most of the damage, but he felt it, bad.
Sort of like a “Spirit Wrack” that those nasty wizards use on us demons…
