Faerie Mysteries Initiate is freakish but it's a reasonable choice for any wizard in a game where it's allowed. As a side effect, it makes the loss of Con from GSA 10 irrelevant. So, Wizard 15/Green Star Adept 10 with FMI is fairly good---20th level spell access, caster level 25, with 15d4+10d8+20+Int bonus*25 hit points, and a boatload of immunities.
