If I have a Colossus and Kitty Pryde with zero tokens, and use Charge as a non-free action to make a vanilla attack as a free action, can I use charge as a free action and then make a vanilla close combat attack as a free action again?

Or would this violate the rule that you cannot use free actions to activate the same game effect?

Did the Working together vanilla attacks ruling basically create a caveat saying "vanilla close and ranged combat attacks [actions?] don't have the 'no two things' rule apply"?

As written, no. However if you have Flurry or Exploit Weakness you could use that for one of the attacks and a vanilla attack for the other. Or Flurry for one and Exploit for the other if you have both.

Nope, Team Bases are a special broken snowflake. Even Multi-attack can't give you two vanilla attacks.

Yes, you can. It has been ruled on previously that if you get to start an action, you get to do everything that that action includes. So because you are allowed to use Charge, you will get to use the free close combat action even if you've already taken a free close combat action during the turn.

found this on another site saying you can use the same effect for multi-attack.

That is incorrect. Multi-Attack follows the same rules of activating free actions.

The Player's Guide entry is old and was accidentally left in. The Change to the PAC and Player's Guide actual wording of Multi-Attack is what you go off of.

@ Vanisher, where in the rules is this?

Such a thing would suggest that you could charge exploit weakness (not free charge) and then charge exploit weakness (Free charge), which I am pretty sure is incorrect.

You could not use Exploit Weakness twice, but you would still get the free close combat action from Charge and with that at least a vanilla attack.

That would be pretty awesome. Do you have the link for that?

This is true assuming the free close combat action you took from your first Charge is used for an action other than taking a vanilla attack. If you took a vanilla attack with the first charge you would need to take a different action(say Flurry or Exploit) with the second one.

This is much the same way you can't choose to take 2 vanilla attacks with Multi-attack due to the multiple free action rule.

Which really should get changed back/fixed (something like characters with can activate the same game effect with multiattack) because Sentroid is the figure who broke it, and my beloved Master Mold got nerfed into nigh-unplayability thanks to that. He usually can't make two attacks, and he can never double-factory.

---------
The no repeating free actions rule applies to everything that doesn't explicitly say it doesn't apply. Only Team Bases can make X number of free normal attacks, because Working Together specifically allows it.
