So I have already made plans for how I am going to go through TH9 once I get there. Where I stand now it looks like I could be at TH9 in a month or so. I have decided to gem ALL of my defense upgrades for TH9. But with a twist. As you all already know, that would cost an insane amount of money and gems to do. So, I have made some adjustments. With the help of the wiki, I calculated the amount of gems needed if I gemmed each defense at a certain time in the upgrade. What do I mean? Well, instead of gemming a defense like a cannon right when I start the upgrade, I will actually let it upgrade for a few days and then gem it. To give you an idea, I will explain how I will gem cannons. They take 5 days to upgrade to lv 11. So, I will let each cannon upgrade for 3 days before gemming them. This would leave 2 days, and thus making the cost of gems only 383 per cannon. I calculated that this would cost a total of 16,200 gems for all the defenses. I will post all of my calculations below:
EDIT: I am going to save up most of these gems from achievements and such, not buy them.
1915 gems – Cannons (2 days left for each cannon)
2 days = 383 gems
383 x 5 = 1915
2298 gems – Archer Towers (2 days left for each archer tower)
2 days = 383 gems
383 x 6 = 2298
1149 gems – Mortars (2 days left for each mortar)
2 days = 383 gems
383 x 3 = 1149
2024 gems – Air Defenses (3 days left for each Air Defense)
3 days = 506 gems
506 x 4 = 2024
1532 gems – Wizard Towers (2 days left for each Wizard Tower)
2 days = 383 gems
383 x 4 = 1532
2024 gems – Hidden Teslas (3 days left for each Hidden Tesla)
3 days = 506 gems
506 x 4 = 2024
*Xbows - This is the complicated part because they are new
766 gems – Xbows (2 days left) - Building them
2 days = 383 gems
383 x 2 = 766
766 gems – Xbows (2 days left) - Upgrade to lv 2
2 days = 383 gems
383 x 2 = 766
3726 gems – Xbows (0 days left) - Upgrade to lv 3
14 days = 1863 gems
1863 x 2 = 3726
Grand Total – 16,200 gems
What I want to know is could this be done?
