I skimmed through the 900+ post and couldn't easily find an answer.No. You take each action once. That's been established in multiple threads -- although yes, there are a lot of threads for this game, so I'm not surprised you couldn't find it.
If I take the bolster action for example. I pay 1 coin and increase my power by 2. Can I pay 3 coins and increase my power by 6?
Same as paying 2 metal to deploy a mech. Can I pay 4 metal and deploy 2 mechs?
