About a week ago, I found myself short on supplies all the time, to where I can only do tournaments or the Spire, but not both. In the Spire, I cater for all stages except the first one. But now I'm short on supplies, so catering uses too many. I can make enough troops for tournaments, barely.
I didn't use to have this problem. I'm now giving priority to upgrading my workshops, but this is hindered due to lack of supplies and space.
Where did I go wrong, and what can I do to fix it?
Dit your culture bonus drop?
Dropping from 150% to 125% drops a lot of supply production.
As some have advised you need maxed out workshop, and premium workshops are totally amazing if you can spare it.
The crazy part is that the tournaments are a self propelling pendulum.
The tournaments give 1 Power of Provision spell each 1st round province past province 9 (so from 10 and onwards) and 1 Ensorcelled spell in each 4th round from the same provinces onward.
These 2 spells are amazing supply (and coin) generators
Lets start with some numbers to visualise things
In chapter 6 you can have a level 17 workshop
Regular workshop level 17:
Regular : 1160 p/h
Culture 125%: 1450 p/h (+25%)
Culture 150%: 1750 (+50%)
Culture 175% (5 ensorcelled active): 2030 (+75%)
Now lets use a power of provision spell (PoP)
PoP spells also improve the culture bonus part of the production not juts the base
Regular : 3480 (+200%)
Culture 125%: 4350 p/h (+375%)
Culture 150%: 5250 (+453%)
Culture 175% (5 ensorcelled active): 6090 (+525%)
As you see using lets say 4 PoP spells and 5 ensorcelled per 2 days you can in a very short time produce more than all your workshops currently combined.
A magical workshop has a base production of about double this. and therefore each magic workshop counts for 2 workshops but only need 1 of each spells making it even more efficient by cutting your spell requirment in half.
This massive improvement in supply production for 12h per day should be enough to feed everything many times over including spire and the barracks, training grounds and the soon to be unlocked marcenary ground.
For this you need to be in a 10 chest fellowship and reach 28 provinces a week.
This might be a challenge in your stage of the game for now but should be easier as you go.
Being inside or searching for a 10 chest fellowship makes all the difference as it's end reward overcome what the first 9 provinces lack so that 28 provinces do reward a net of 28 PoP and 28 ensorcelled per week.
when you can't reach 28 provinces you might be able to do 14 with 2 magical workshops for a similar like result.
As you can see in this case doing more, can make your game easier instead of more difficult. the more your skimp on parts of the game the more difficult it becomes.
