What do i do with slimèeeeeeeeeeeee
What he wrote is not technically correct. It's when an enemy attacks you that you get a shield back. How long your shield stays up depends on how much of your base they destroy.
Also, the enemy must win for you to get a shield back; i.e. 50% of your base or more msust go down in flames.
Here's a breakdown:
Enemy destroys 50% of you base: You get a 1 hour shield
Enemy destroys 54.2% of you base: You get a 2 hour shield
Enemy destroys 58.4% of you base: You get a 3 hour shield
Enemy destroys 62.6% of you base: You get a 4 hour shield
Enemy destroys 100% of you base: You get a 12 hour shield.
Theoretically, this is how it should go down. There are definitely some other factors that play into it because I've been attacked 3 times in a row by different players less than 3 minutes apart, they all lost and somehow I wound up with a 1 hour 45 minute shield.... so unless the developers want to shed some light on this, I'd say your safest bet is to spend all your cash and mana before you log off so it doesn't get thieved away in the night when your shield is down. Unless of course you are saving up for something big....then you'll just have to put up a good defense and pray that your panda sits on their faces.
Click on your Hero Altar, click on the hero whose skill you want to level, then press the UP arrow button next to the skill, then press on the slime and/or extra hero you want to sacrifice to add them to the "sacrificial altar" and click the shiny Upgrade button. Boom, you got your self a brand-spankin' new upgrade (if you shed enough slimy blood and hero guts)
Hey man, great job on the extra details. You def need to edit this post though to reflect how shields are actually activated. Your 12 hour theory is misrepresenting what actually occurs. Check my previous comment in this thread for details...I laid it all out.
