If we could get 50 low-to-mid level crafters, or even just 25, a lot of really nice options open up for us, and I'm not talking about from the mega-project standpoint that
@Azel wants to start them on.
This month, we're crafting three of the MirrorVision mirrors. Each of them costs 2,880 IM and even with her discounts, that uses 26 days of Valeria's crafting time. If we could assign another five crafters to producing those, even without any discounts, that would be another eight Mirrors. We could have one in every city, settlement, and Scholarium branch in the Imperium in just a few months.
A few weapon crafters would let us start stockpiling enchanted projectiles. A single such crafter could produce 300 or more +1 Bane crossbow bolts (Evil Outsiders, Aberrations, Undead, Fey, whatever the fuck the Others are, etc) per month. Scale that up by five and we could produce 1500 or more projectiles per month. This is how you wage wide scale warfare against an enemy as entrenched and powerful as the Others or the Deep Ones. You make it so that even the least of your forces are a threat to them.
A single additional crafter capable of creating Constructs would let us put 266+ Lesser False Ravens into service each month.
@Azel What would it do to the cost of maintaining the Legion if we crafted enchanted items that provided all of their food and water without any need for the complex logistics involved in feeding so many soldiers? Or even if we were only able to reduce it by 25%?
In just two or three months every important official in our government, every Inquisitor, Legion officer, Scholarium Initiate, etc., could have a PfE item and Healing Belt.
TL;DR 50 crafters ready to work would be amazing.
