Which way is “that way”?
What robb8888 posted how each Character Card of the Sentinels got a choice of a power use or health gain.
The reason it works that way is because Proverbs and Axioms specifies Hero Character Card and the Sentinels has four Hero Character Cards.
If I’m not mistaken, it’s even better.
Each Sentinel gets to either heal by 2 or deal themselves 3 damage to have the Sentinels collectively use a power.
So for example, you could have Mainstay and Idealist pick heal. Then have Medico deal himself 3 (becoming healing) to let Idealist use Telekinetic Jab. Then, have Writhe deal himself 3 (redirected) damage to let Mainstay use block.
You are mistaken.
Each Sentinel gets the choice of healing 2 HP or taking 3 damage and using a power. The wording of Proverbs and Axioms reads: "Each hero character card [as opposed to "each hero"] may either regain 2 HP or deal themselves 3 psychic damage and use a power."
In the context of the actual One-Shot (a Vengeance match against, among others, Advanced Fright Train), it was just sick. Advanced Fright Train channels "all hero damage" to himself. That includes – as it turns out – damage the heroes inflict upon themselves.
I had Scholar play Proverbs and Axioms on the very first turn; with eight "hero character cards" in play (Guise, Wraith, Tach, Scholar, and four Sentinels), that was eight extra power usages, with three damage for each usage inflicted on Fright Train. The Sentinels had previously played one of their AOE cards; between that and Proverbs, Fright Train went down before the environment's first play.
Are you sure? I just replicated in the video game. Should I send a bug report?
Here's the relevant portion of my log file:
Edit: that formating looked awful see attachment.
I wasn't sure who you were saying is mistaken.
This thread seems to be suffering from a lack of specificity in its statements. 
If only there was some sort of feature that one could click to allow everyone to know who the poster is responding to. Perhaps it’ll be added in th massive website update?
Unlikely
The person who said directly above my post, "If I'm not mistaken." Sorry I thought that was clear.
Dandolo, that would be a bug.
No need to send in a bug report - I reproduced it locally and we'll get it fixed.
Yeah, as I understand it, first, if Medico's damage becomes healing, it doesn't trigger Sentinels Tactics, because he didn't deal any damage.
And even if he could, it only triggers the first time a turn, so Writhe's self-damage couldn't let Mainstay use block.
No, but he “dealt himself damage” to use a power, per Proverbs and Axioms. There’s no Rule 15 wording, so it works. Medico and Writhe aren’t activating Sentinel Tactics, which is where you guys are getting mixed up. They’re just doing what they are supposed to because of Proverbs and Axioms!
And since it doesn’t say use a power ON THAT CHARACTER CARD, when Medico tries to deal himself damage, The Sentinels get to use any power, Including The Idealist’s. Then HER damage triggers Block with Sentinel Tactics. Then Writhe deals himself damage per P&A – which may or may not get redirected – to trigger M.D.
There’s no bug there. Each power is used once, and every card is obeyed. You’re mistaking the powers from P&A as being multiple uses of Sentinel Tactics, which is not the case.
It is working as it should be. Do not change it.
Per MigrantP and I'm assuming this will be laid out in Fireside Chats if the individual Sentinels member chooses to take damage then that individual member can use the power on their character card, a power on a card attached to them, or a power of a card in the Sentinels play area. In other words, I can't have Idealist take the damage then have Mainstay use a power off of that. The self damage would trigger Sentinels Tactics if it's in play but if Idealist uses her base power off of that then likely she has no other powers she can use for Proverbs and Axioms.
Right. That’s exactly the situation laid out.
Mainstay heals. Idealist heals. Medico takes damage (which becomes heals) to use a power. He uses Idealist’s power. Tactics triggers, allowing him to use M.D. Then Writhe takes damage (which gets redirected away) and uses Block.
No double dipping on powers or Tactics. It follows the rules, and is NOT A BUG.
No. What you listed out wouldn't work. If Mainstay heals, Idealist heals, then Medico chooses to take the damage and Hippocratic Oath is out then Medico heals a target and can use the power on his character card. Then Writhe has his choice on healing or taking damage. If Hippocratic Oath isn't out when Medico decides to take the damage then Sentinel Tactics triggers and you can choose to use any of the Sentinels powers. If you chose Medico's power due to Sentinel Tactics then he likely has no power option.
This should work along the same lines as Gung Ho. The individual Sentinels member which gets healed can only use the power on their character card.
I'm assuming in both of these cases that none of the Sentinels have any cards attached to them or in their play area that grants another choice for a power.
MigrantP has also already confirmed in this thread it should work the way I've laid out and what happens in the video game currently is a bug.
That’s literally the opposite of what you just said 2 posts ago.
And now you say that’s NOT the case. Which is it? Block is in Medico’s play area, and they’re the same hero, so why COULDN’T that work?
Because…comic books? (Is this the right thread?)
