Eldritch Niche - Spell Twisting Questions

[Blazej]

I was running a spellcaster running alongside an eldritch evolutionist and I did end up having some questions on how the spell twisting ability worked in a number of unusual cases. I went with the GM decisions, but I wanted to mention the questions that came up.

Generally I have made the assumption that the only things that spell twisting changes are spelled out in the ability. That anything beyond the immediate targeting, range measuring, and attack rolls required when the spell was cast instead falls upon the actual spellcaster.

Question: If an evolutionist uses spell twisting to take a spell that centers on the caster (e.g. synaptic pulse) is the evolutionist excluded from the effect.
Assumption: Made the assumption that the spell excludes the evolutionist themselves, just like they were the caster. Although at the moment, I admit I can't find any rule reference that clearly states the spellcaster would exclude themselves from their own spell effect either.

Question: Can a evolutionist take a personal range spell with spell twisting? For example, if an allied spellcaster casts see invisibility, could the evolutionist use spell twisting and then benefit from see invisibility until the duration ran out?
Assumption: Assumed that they could. The evolutionist is just targeting themselves as the caster.

Question: If a evolutionist uses spell twisting on a spell and then targets themselves, does the caster then need to roll to beat the evolutionist's spell resistance?
Assumption: I would think yes based on the limited items that spell twisting states it affects.

Question: What happens for spells like junksword? What benefit does that provide for the spell twisting evolutionist?
Assumption: I assume that the spell would not work in a meaningful way. The evolutionist would make a junksword that they couldn't use, because only the spellcaster/creator can use it and gain proficiency.

Question: Can a evolutionist use spell twisting if the spellcaster is casting a spell from a spell gem?
Assumption: I assume yes in that activating a spell gem is referred to as "cast the spell encoded within the gem" and all spell twisting needs is an ally to "cast(s) a spell". In that same way, I assume that spell twisting can't be used in reaction to a spell ampoule, as those are injected and you don't cast a spell through them.

you choose the spell’s targets, measure the spell’s range from
your space, and make any attack rolls for the spell as if you were the
caster, though the original spellcaster makes any caster level checks,
rolls any damage, and is responsible for controlling and concentrating
on any subsequent effects of the spell. If you succeed at the save, you
can redirect the spell as if you had failed, but you also apply one of the
following three special effects to the spell.
D D You increase the spell’s saving throw DCs by 2, to a maximum of
10 + 1/2 your evolutionist level + your key ability score modifier.
D D The spellcaster’s caster level is treated as 2 higher for the purpose
of overcoming spell resistance, to a maximum of your evolutionist
level + 1.
D D If the spell deals damage, you can replace your adaptive strike’s
damage with one damage type dealt by the spell until the end of
your next turn. This effect does not change whether your adaptive
strike targets KAC or EAC.

being ignored, no you would not be ignored. You are not actually casting the spell, you are a valid target.

Personal, you are not the caster so no, you couldn't benefit. You target choices are basically the Spell caster or the Spell caster.

You are a target of the spell, so SR would count since you are not classed as the caster, there for its not a personal spell.

Junk sword. You get to chose the junk.

Spell gems, work as a spell

This is obviously my view on it

Good questions! Hopefully the final turnover addresses some of it.

One question my group came across: how does the DC bump interact with spells that allow saves in subsequent rounds, like Infect Blood, Psychokinetic Strangulation, or Baleful Polymorph? Do they benefit from the DC increase in subsequent rounds?

[Wesrolter]

I think they would stay the DC as the first casting, I don't think the DC of an ongoing effect is changed if the caster suffers an effect.

Since
"you choose the spell’s targets, measure the spell’s range from
your space, and make any attack rolls for the spell as if you were the caster"

I interpret that you can apply personal spells onto the Evolutionist, since you are considered to be the caster when determining from where the range is measured and "personal" is a category under range.

Here's all the relevant text I could find on range and personal.

Range wrote:

An effect’s range indicates how far from you it can reach. An effect’s range is the maximum distance from you that the effect can occur, as well as the maximum distance at which you can designate the effect’s point of origin. If any portion of the effect’s area would extend beyond this range, that area is wasted. If a range is based on level, this means caster level for spells, class level for class features, and item level for weapons and equipment. Standard ranges include the following.

Personal wrote:

An effect with a range of personal is limited to and affects your person only.

Saddly, they don't really clarify the issue any further. Although I personally believe it is intended to work as I said above, I strongly believe there needs to be a clarification on this matter.
