... it's a 25% random, not a .04% :V The daktyls only need D1 to start forging staves -- master smith bumps up it up enough. The .04% is only if you want them to cast it natively, which... yeah, I wouldn't be holding out for that. I didn't even notice they had 110%, ha.
The research is pretty troublesome, yeah, though you only need cons 4 to start staff forging. For what it's worth, your starting army can do some pretty good work -- the spectrals tear up most UW PD, from what I've seen, with about the only holdout being amber provinces -- and keep things rolling until you've got what you need to jumpstart that part of your army layout. Kept for posterity: In which Frumple's memory leads to silly statements.
... though actually checking things, now I'm wondering why I thought you needed skull staves or D2. The base freespawn summoner summon is only D1, and once you have the one D1 smith, you can have it summon revenants (which is only ench 3) to summon more ephors, if you actually have the surplus of gems to bring in more spectre callers. Otherwise it's just setting the smith to summon more ephors. So all you need is a (slightly more than) 25% random to start off your undead production. Everything else is gravy. Which innit too bad, really. Conceivably it starts at turn two or three, if your pretender has no D and you alchemize everything into death. And luck out on your first daktyl being one of the 1/4th D randoms.
So, double checking things, I'd probably argue you don't need an awake SC* pretender for early game expansion (though you likely still want one, because while taking one/turn is nice, taking two/turn is better), so long as your start army avoids priest provinces (and maybe if it doesn't, if you send along a prophet), you don't need the SC to summon ephors -- daktyls manage that just fine, if the RNG isn't being a complete jackass -- you don't need your pretender to do sitesearching (daktyls, again, should manage, and are your best native sitesearchers anyway). The bless is a definite thing, but you're dealing with a domkill nation so you'll probably tank your scales (except magic and luck, the latter of which you'll probably end up relying on for income) anyway, so you've got what you need, there.
*Which... looking at it, your cheapest chassis can probably manage that easily enough, if you're okay with a water/astral bless (actually pretty decent for your ethereal sacreds!). W9S9 awake floating brain, 7 dominion, 2 Turmoil 3 Sloth 3 Cold 3 Death 3 Luck 2 Magic? Cash income will be shite, but that's what the ephors are for.
