The Noctuary (D&D 3.5e, Level 20+ Adventure)

[Burning Spear]

Spell domain could do it as well, provided you could cast 3rd level spells and used anyspell to prepare charm person.

The Customize Domain feat could as well. Probably other options too.

Spell Research seems much easier 🤔🤣, my choice of domains seems kinda fixed, except for Storm domain,which there for thematic fun, which could be exchanged for Elysium, IF allowed by the DM, however; Elysium demands N.G., Mindbender demands non-good...
