Double tapping attribute boost Options

[sunnyside]

I'm helping a new player with a character and they're looking to have a single boostable attribute.

I was thinking of close combat, and how you can't do much with a simple action there. So what could they do with a spare simple action if they boost?

What about boosting again? I could see a couple ways this could work.

1. They stack bonus but not time (alowing you to go up to your racial maximum)

2. They stack time, but not bonus.

3. They operate simultaniously, but don't stack. So essentially you're just taking the better of the two.

4. You have to "cancel" the first before trying a second.

5. You can't cancel have to wait until it runs out to try a second.

In all cases you still take drain from both.

Personally I'm leaning towards 3.

If not 1, 2 or 3 can you think of something good to do in CC with a simple action?
