"Alrighty then- that's good and all, but just a warning- immortal characters are a lot more difficult to write well, because their lives are never truly at stake."

only if you use True Immortal / Invulnerability.. which is the boring type.. like if you made a story with a True Omnipotent.. that's why almost all media has "semi-immortal" / "semi-omnipotent" instead.

Inferno's immortality is below that of an Absolute, he will shrink down to "Mini-Inferno" if he gets too beat up.. at which point he stays that way for a few days, then grows back to normal : enchanted attacks or extreme violence can scar him permanently however (such as what happened due to continued beatings by Equinox).

Ebonscale's link with his son has the drawback of the fact he can't survive with Inferno, so ultimately becomes parasitic (like Carmine, Misery etc) - especially after the bonding.. also after Inferno and Ebonscale bond (post-Monsters) a voyage will be taken that will ultimately remove the curse and separate the two - ending the whole "father/son" bond and allowing one or both to die for good.
