Weak should afffect bosses, albeit not by 50% lower damage

As in title, weak cards are generally a very weak choice late game wise, since bosses are resistant to it's effect. It creates weird feeling, since many rare cards apply weak and are generally considered to be a "prize", but they are inherently a bad choice that doesn't pay off if it doesn't apply weak effect.

Solution would be weak lowering bosses damage by something like 20 or 25% damage, so the card pays off for itself, but doesn't make the fight trivial.

I agree that this is a minor issue. Bosses of all kinds are the prime reason you would want to play cards that weaken them (to a lesser extent, that also goes for Decay), whereas if your party has a reliable shot at the bosses and winning the campaign, your overall (defensive and offensive) output against normal enemy groups is likely high enough that you tend to rarely make practical use of those two curses.

Having the few enemies where it would feel really powerful to utilize be completely immune to the effect disincentivizes getting those cards at all. Perhaps Weak should simply just be 30% in general but a bit more common to get and work on everything. That way a deck strategy that tries to keep Weak stacks on a boss is a valid defensive strategy similar to having lots of Vitalize or Block/Shield.

I like the 30 % againt everyone idea. I was looking at the Demoralizing Shout card, a purple warrior card costing 3 that only does weak to every monster. That would be a completely dead card againt a boss, so not worth getting.

I mean, between buffing your own resistance(Reinforce etc.), Block and Insanity stacks on the boss, you can already downgrade them to negligible damage.
Personally I do not see the need for more, without completely trivializing fights.

During a run(especially at higher madness) more of the act 3 and 4 encounters will be tough and powerful enough to the point where Weak will have an impact(while they usually wont live long enough for massive stacks of Insane).


As for Demoralizing Shout, it applies both Weak and Vulnerable with the base, Yellow and Purple upgrade, and will be a very effective debuff against various encounters including bosses(you can usually stack Vulnerable on them, and most bosses have minions or summons, which are usually not immune to Weak).
It is only the Blue upgrade that does not apply Vulnerable, to compensate for not having Vanish. The Blue upgrade is a very specialized upgrade choice.
