I'm pretty sure I made the right call on this, but I wanted to verify. The Scholar has quite a few cards that say "When the scholar is healed...". For instance, one card says something akin to "When the scholar is healed, he does the same amount of damage to one other target."
What happens when Scholar is at maximum hit points? The way we played was that he doesn't actually get healed, since he has no damage, and the cards subsequently don't fire.
To give a specific example, we had Scholar and Legacy on the battlefield. Scholar had one copy of the card that says "When the Scholar is healed, increase the amount that he is healed by 1" and two copies of the card that says "When the Scholar is healed, he does the same amount of damage to one other target." Legacy used his power to increase all damage by 1, and Scholar was down exactly 1 hp.
Thanks to the ring that allows Legacy to use two powers, Legacy was then able to use the power that smacks someone for a few points of damage and heals all heroes for 1hp.
We played it as follows: Scholar is being healed for 1, so due to the first card, he is now being healed for 2. Unfortunately, since he is only missing 1 hp, he is actually only healed for 1 point of damage. From the second cards, he has now been healed for 1 point of damage, so each allow him to do 1 point of damage to 1 target. Legacy's +1 to all damage increases both of these to 2 points of damage, for a net result of 4 points being handed out.
On the next turn, Omnitron X was ready to use his power that heals three different targets for 1 point each, but since the Scholar was at full, using that on him would be a waste.
I believe that that is correct. I think you actually have to regain hitpoints for it to work. I'm not 100% on this, but that is how I would've played it.
A lot of the Scholar stepping too close to a grenade launcher's target, or stepping into the way of a well thrown knife, you know stuff happens when you haven't been working in a team before, you tend not to know where to go. Or maybe Expat didn't care to hear those lovable axioms as much as he thought, and let's him know with a shot of her own unique tact. Chain Lightning is always unpredictable, and Haka does get carried away sometimes. Now if James Brooks is putting bounties on the Scholar, well then you have to wonder whehter these situations are really accidental or if they really weren't joking when they suggested he might want to wash that robe.
I like to think that the heros are blasting Scholars Liquid Energy form with more energy that he then unleashes on his turn. Or maybe it could be them accompanying a ritual or something with the Philosophers stone which takes its own toll on Scholars body (his powers can't be without their downsides, it is the philospher stone after all).
The second quote was around taking a hero out of the game in order to provide that one ability that would help the heroes. That's a hard one for me to justify thematically, so I'm not likely to do it. Doesn't mean I won't, just not likely. (Hence "…not sure I'd be willing…")
Attacking another hero, though, to facilitate them doing something? That makes sense. Think of Avengers, when Thor hits Iron Man with lightning in their initial meeting, overcharging the suit and letting IM nail Thor with his repulsors. Later, they are working together. Thor plows the field with lightning, including the big bad and IM, leaving just the big bad and IM standing. IM cuts loose and takes down the big bad. (Still disappointed we didn't get to see that in the later fights, but still hoping it'll happen next time!) Or when IM fires at Cap in the final fight, and Cap reflects it to hit a bunch of thugs.
They know how they can work together and be better when they use their abilities on each other and how those abilities interact. That's interesting and smart.
