Hmm. Ah, right, Caelum has 'Seraphine' not 'Seraph' so no problem there. Problems should only occur with ambiguity... heck, you can probably wish for an Abductor if you want to clone Tjatse the Niefelheim hero. Not bad, although if you want more arms then Kailasa or Lanka summons/heroes would be better.

The Chalice, the Sceptre of Dark Regency (+3D for 40 gems and only a single hand slot!), the Flying Ship, the Hammer of the Forge Lord / Hammer of the Cyclops might be worth it if you lack the mages to build 'em or somebody beat you to them. The Sceptre is particularly nice for a Tartarian factory -- +3D means you need D4, so a Demilich would do, or a Mound Field with a Skull Cap.
