Actually I'm pretty sure the slaves do get boosted for paths they don't have, and in fact can be buffed by ie. phoenix power even if they're just S1 slaves. Just for the purposes of soaking up communion fatigue of course. Now, you're still going to have trouble using smaller numbers of them to cast spells which require a level 3 mage (like blade wind), even if they're boosted up to 2E they're still taking double fatigue from it and it's an 80 fatigue spell. That adds up fast if you're splitting it between say 4 slaves...
