X can use Regeneration. If X has no action tokens, then this is FREE.

Does this mean that X can use Regeneration as FREE, and then as a POWER, in the same turn? Or can only use Regeneration once per turn?

Which character is this?

Can you quote the exact power or are you trying to create a custom power?

The second one.

From my understanding, the ability is setting up and if/then statement. So the character would be able to use Regeneration OR they would be able to use it for free.

If you want it to stack, maybe something like “Regeneration. FREE: if this character has no action tokens, Regeneration.”

X can use Regeneration twice per turn as you described. Even the other way around if you can remove X’s tokens after given POWER.

Not quite.

First sentence allows Regeneration (as if it were displayed normally)

Second sentence creates a condition where using it is FREE (instead). As long as the same FREE action wasn’t given twice it’s within the rules.

If we wanted only conditional Regeneration as FREE we would remove the first sentence only.

‘When X has 0 action tokens Regeneration as FREE.’

The above only grants Regen as FREE so the POWER version can’t be used unless granted by another game effect.

Thanks for the replies. How about...

X can use Regeneration. If X has no action tokens, then this is FREE instead.

Then unless X is given/removes an action token via another game effect it would only be able to use Regeneration once per turn.

Extremely close wording. The only difference is a penalty when he Regenerates for free.

Swell; thank you!
