You'll get back 20% of what you spent. I.e 25b the level 2 upgrade for t5 level 2 (50b) total is 75b. You'll get back 15b.
Does a volary level 1 give less Ally Bonus than SoS level 1? Just changed an sos for a vol and coulda swore it went down.
Monkey, if it went down, it didn't go by much. SOS are weird. It goes up until 12 I think, then goes down until like 19-21, then goes back up. Idk. That's how I was told. My ll are complete SOS and my hl have 11 vols. I didn't really watch the allies bonus much.
SoS 1 has higher plunder than Vol 1. I am currently converting my SH alt to a Hansel, and am loosing plunder.
Yes, spy buildings have an affect on attack plunder. They will change your Allies bonus, but not your Plunder bonus.
After you upgrade your castle to lvl 3, the Mage will become available to enchant equipment. Certain equipment cannot be enchanted.
