For some missions, yes, but you'll need to have very high stats. Don't expect to solo anything higher than series 3, however.
If the entire clan is active, possibly, depending on how the split of how much of the clan does what. Different actions award different amounts of gold, such as scouts making less than a steal, and steal success making less than an assassination (since you earn gold on steal and at end). Item gold depends on the mission/item used.
No. Gold is earned individually, so if someone leaves, they take the potential gold they would have gotten with them.
I just got an idea. If you were the owner of your clan during an epic battle, if you reset near the end, would you get all of the reward that you earned?
If I used over 1k sleeping potions on the mission "the deprayed" will it give me more of a bonus at the end verses only using 200??
How many are there? Nvrmnd you probaly already answered that but u can do it again. One monster how many battles.
Yes, and type of action. Like scout successful actions pay less than steal successful actions which pay less than assassinate successful actions (since on steal you earn gold from the action immediately)
Yes. In one of the early missions yesterday despite only having maybe 100 mil in allies, my attacks/assassinations earned me over 300mil in reward.
J3acon said this in CC at the end of the last mission, since he's a small build: "WHOA!!!! 388mil for 300 mists of confusion!" "with some assa, fights and steals. but that usually gets me <50mil" "I upgraded 4 guilds, got another land and started on max plunder. those mists were really profitable" This was on the mission before The Depraved I believe ^^
