We can use our charms, including rage recast, but I am doubtful that we can stack them. Swift Stride can't be purchased twice, unlike Hardened Devil Body. So, if we have it in shintai already (I don't remember if we do), I highly doubt we'd get benefit of two of them. By buying By Rage recast we would be unlocking it in our base form, but not doubling it in our shintai form.
Uh, yes it can?
At least nothing says it cant, and the Shintai rules are explicit about telling us when something doesnt apply, like us not being allowed to buy Hardened Devil Body as a BRR Aspect.
At this point with one of the main contenders for plans being a 4 point plan I think it makes sense to round up
As for BRR, in terms of fluff what that charm does is bring part of your shintai into your normal form, so if you have the power to do Agg as a shintai you get it with BRR, but just because you have the charm the weapon does not get even better Agg, even hotter fire. If you got let's say 2 extra arms in Shintai and then got BRR you would not then have four arms in Shintai IMO that was not the intent of the designers
Thats actually appears to be the intent tho?
You stack Demon Armor for more soak, or Hardiness for immunity to different environments.
Even the specific example you cited:
The Shintai possesses more than the normal comple-
ment of arms and legs, or perhaps sports a prehensile tail
or trunk, or perhaps can manipulate its immediate sur-
roundings with telekinesis. When the Infernal takes mul-
tiple actions, each subsequent action raises its difficulty
as normal but doesn't suffer a penalty to its dice pool.
Doesnt raise any limits.
Think Asura from Asura's Wrath for a visual image, if youre not fluffing it as TK or Doctor Octopus-style tentacles.
And its not like the speed is an issue, when we apparently have arbitary movement speeds underwater due to the ruling on Rendered Villain Dispersal.
This doesn't make sense first you say that Lash isn't a member then in the next sentence you admit that she works for them.
I dont see the issue in my explanation.
Lash is a copy of Lasciel. Lash(currently) works for Lasciel.
Lash isnt a Denarian. She isnt a member of the Denarian organization.
She doesnt take orders from the Denarian organization. Or give orders to them.
Hell, the Denarians themselves are quite factional, and Nicodemus faction works as a separate organization from Lartessa's faction most of the time. Lartessa's minions dont take orders from Nicky. Never mind the independents.
Denarian is more a type classification than a functioning organization
