This only work if your alliance has a butler
PM the butler,
With the following command:
"
!restrickle 'castle link'
"
Inside 30 minutes, the butler will answer you with a list of castles from 0 to 60 fields from your castle. You will use these castles for your resource trickle
Resource trickling is sending 1 resource with 55 units at crossbow speed to castles at each distance from 1-whatever fields. Crossbows take exactly 10 minutes per field if you don't have map of the area (I specifically haven't done that in any castle for this purpose) 9:30 with it which still works.
The only down side is you can't check for holes easily, because it doesn't show when they get back until they are on the return trip. It takes about 12 minutes to build 2-3 hours of trickle, and most of that is waiting. It's 20 minutes per field round trip, so you do it once, and then wait ten minutes and do it again.
The best part of it is that you can wait and see if it's real first before you do anything. No wasted time or troops. Waiting on the butler to give me a list, I'll explain more at 10:30
So I would just go down the list, sending 55 Xbows, or 1 Xbows and 54 faster units, with 1 resource. Every three fields is one hour of trickle, it adds up very fast.
Try to count out how far you can go before you use half your available units ahead of time. Use up half, wait until ten minutes from your start time has passed, and do the exact same thing again. Done, hours of trickle.
