When my Wanted monster mission chest is in cool down, I am really really liking farming s1-7-7.
You get Rugged clothes for Extra fast training. Extra fast training is second best XP per recruit, but its XP per hour is 66.6 times faster than Extra low cost training. Extra fast training is also the best +special skill roll per XP. This makes it ideal for your last training camp ( “Delta”), you can alternate Extra fast ( speedy ) and Extra low cost ( most XP ).
Wooden shields from s1-8-7 are only used for Elite training ( RT13 ). Legendary training ( RT20 ) is better for summoning 4* heroes while Guaranteed rare training ( RT12 ) is better for storing food ( if you need zero 4*/ 5* heroes ).
String for Arrows. The only battle item that lowers accuracy. It can be stacked with Axes/ Bomb/ Dragon items.
On autoplay, it is fast. It produces +30% more recruits per Autoplay hour than s1-8-7. Loot tickets are still faster, but there are currently no good farming areas for recruits costing 6, or 9, World energy so you consume a lot of Loot tickets.
