Its one of my favorite charms. Very excited to play a character who's constantly pulling out new artifacts from discarded timelines to battle my foes.
You could arguably use the Hearthstone merit to summon an entire building whenever you need one.
Personally, I think Summoned From Time should only pull social merits like Allies or Command, because as it is it steps on the toes of a couple other cool charms which summon Artifacts or Hearthstones from the Getimian's Origin. It should probably be a mote commitment, too, to be honest - in its current state, I feel like it's overtuned.
I
definitely do not think Summoned From Time is intended to let you summon manses: both because that seems absurd; and because that
very much is stepping on the toes of Demesne-and-Manse Emulation, which explicitly conjures a Hearthstone and makes everything out to extreme range a part of the Getimian's domain - which in turn implicitly suggests that Summoned From Time is not intended to do that, and should only be summoning the Hearthstone proper, not any of the infrastructure.
If I had any input into the editing of
Essence, Summoned From Time would commit its motes, and only summon Allies, Familiar, or Command - it pulls
people to help you, with the attendant angst of them fading back into the Beyond at the end of the scene. Go ahead and keep the option to purchase them, though - wordcount permitting - I would probably like something like "1 Exalt Milestone for a Tertiary Merit; 2 for a Secondary; maybe 3 for a Primary?" And while there's no way they have the wordcount for this, I think it'd be cool to be able to pay in installments - to be able to only pull someone partway into Creation, or only part of your army or whatever; and have them function at a lower Merit rating until you spend the additional Milestones. Not sure I like that a Getimian can just create 5-dot merits arbitrarily, as currently written.
Unforged Masterworks summons Artifacts - in its current state, it already does what
@Red Orion wants, i.e. allows a Getimian to conjure a new artifact weapon every fight (personally that would annoy me? But I guess if your ST is fine with it, who cares what I think?); while also (via the repurchase) supporting players who want their own cool, unique Artifact that, you know, functions as if they had actually bought the Merit and can gain Evocations and all. I think it works fine. No major changes I'd make.
... and, um, I'm not entirely sure what is
meant with Demesne-and-Manse Emulation (the Getimian mode of Prismatic Arrangement of Creation Form)? Like, "everything out to extreme range is the Getimian's domain." Sure. But -
The absolute strictest reading of that is just that the Getimian can automatically detect Essence expenditure within extreme range, which is, you know,
fine. It's useful.
The
cooler and more thematic reading is that Demesne-and-Manse Emulation actually summons the Demesne or Manse for the duration - a bubble of the Getimian's Origin, displacing, for a brief time, the dross of this Heaven-marred Creation.
I like this because a) it means that this is an "instant boss arena" charm, which is frankly just cool and awesome spectacle; because b) it's thematic - the pinnacle of the Getimian form of the SMA based around understanding and emulating the bones of Creation is saying 'fuck off Creation, we're fighting in my
better universe now''; and c) because it gives an excuse to make the innate power and possibly the Evocation of the Hearthstone granted by the charm into Lair Actions.
...So obviously if I were in charge of editing
Essence, or running for a Getimian martial artist, I'd go with the second reading.
