Prodigies can be armor, but it's described as Pushing it in terms of passives though. Just because they can doesn't mean they have exclusive dominion over the concept though. Splendors can be pretty much anything because they're supposed to be weird pseudo-artifacts.
In any case the stuff @Yog has designed is a pretty direct application of the rules for making this kind of stuff. You can't reasonably argue they're breaking the rules in their principle effects.
Splendors are described as congealed sorcery, weird magic shit from the Age of Legends.
Routine soak is not supposed to be their function, and they consume valuable and rare reagents to make, in a way that Prodigies and Arcana do not at the lower tiers.
Im beginning to think Im the only person who cares about conserving these things for when we need them.
Admittedly, Holden doesnt appear to think much of magic armor; you see magic guns and magic swords, but dedicated armor is not an example he bothers with.
You apparently get soak with charms.
Furthermore, the things Yog mentioned appear to cross the line between Can and Should, between inspired exploits and Rule Zero non-compliance.
At a time when the QM is mentioning having trouble with balancing combat encounters, designing equipment along the lines of conferring immunities in a system that doesnt really have them except in limited cases (unlike, say, DnD) is the kind of thing you avoid. See the QM banning the Splendor feature Twisted Horror Curse for much the same reason.
We haven't run into that many things with stamina that high, and anything that does isn't going to be super impressed by the damage of SSB.
Thats my point. SSB is entirely inappropriate as any sort of standard ranged option.
The greater akuma. The Dragon. The big worm in Cleveland. Iku-Turso. The lesser skinwalkers with not!Crinos.
Anyone with high Willpower who can use Steelskin. Anyone with access to an alchemist making boost potions. Any path sorcerer with Body Control 3. Any fomor with the Exoskeleton and Bestial Mutation powers.
Its very easy to reach Stamina 7 in this system, for at least the duration of a fight.
If you have some kind of ability that keys off having done damage to someone it is also good.
True.
Not many of those in the Infernal charmset though.
