Gaze of Two Minds interpretation help

The Eldritch Invocation, Gaze of Two Minds allows you to perceive through the senses of another creature and you can cast spells as if you were in your space or the other creature’s space if the two of you are within 60 feet of each other.

I am curious how people would rule on how this would interact with certain spells and how you would describe their effects in game. 

Starting with spells with a range of self I think it is reasonable to say any of those spells that directly buffs you can only effect you regardless of what space you cast it in. However what about spells that target yourself but interact with where you are like Misty Step and Arms of Hadar. Gaze of Two Minds lets you cast spells as if you were somewhere else so does it let you summon tentacles out of the being you are connected to with Arms of Hadar or let you teleport anywhere within 30 ft of the being with misty step? What about True Strike or Vampric Touch both are self targeting spells that let you make a melee attack so would they have the ability to use the hypothetical reach you would have if actually were in the space of the other being? If so how would that look?

Next what about spells like Illusory Script the spell has a range of touch and has you write on something to perform the spell does this mean you can use the spell to just write on things they touch? Do you need them to follow along? Do you just pantomime writing or do you have to grab another piece of paper? Comprehend Languages brings up a similar question by requiring you to touch the surface something is written on to understand it. Does feeling the surface through the other creatures senses could for the spell in your opinion?

Lastly Suggestion does it project what you say from the space you are casting it from or do you have to say your suggestion louder for the target to hear?

I think you're right that Gaze of Two Minds is often of limited usefulness with spells with a range of Self, or in general spells that say something happens to "you". But here are some thoughts on the specific ones you mentioned:

• Misty Step: GoTM largely affects the range of the spell, i.e., you can teleport to a position you can see that's 30 feet from the GoTM target, even if that's more than 30 feet from where you are.
• Arms of Hadar: you can make this affect creatures within 10 feet of the GoTM target.
• True Strike: I don't think this one works, because you're attacking with a physical weapon that you're actually holding, and GoTM doesn't move that weapon to the GoTM target's position.
• Vampiric Touch: I think you can attack something within reach of the GoTM target.
• Illusory Script: this spell requires you to actually write on something for it to work. GoTM doesn't allow the GoTM target to do this for you, so it's not helpful in this case.
• Suggestion: GoTM can effectively extend the range of this (the target must be within 30 feet of the GoTM target rather than within 30 feet of you). The spell says you need to be able to see the target (though seeing them via the GoTM target's senses is fine) but it also says the target needs to be able to hear and understand you. Not the GoTM target, you. GoTM doesn't give you any special ability to project your voice from the GoTM target's position.

I don't think it could extend the range of your misty step. The effect is you move 30 feet, so you can only move 30 feet. It does have the advantage of being able to get you to places outside of your personal line of sight though, like if your tiny familiar slipped under a door it can see what is on the other side and you can misty step into the room. The location of the cast imo does not matter for it as the effect is on your body and it can only move 30 actual feet.

I think the rest could work, though it may require some setup. like I think true strike could work if the creature was a weapon user, like for example if you had the skeleton familiar. Illusory script if the creature was under your control in some way like your familiar and had the ability to write things. Vampiric touch I'm a little hesitant on, as it seems more like a self buff vs say arms of hadar which seems more like just a point blank AoE. 

• Misty Step: GoTM largely affects the range of the spell, i.e., you can teleport to a position you can see that's 30 feet from the GoTM target, even if that's more than 30 feet from where you are.

And as GoTM has a 60' range on the effect then it upgrades Misty Step to a max 90' effect which is kinda useful.

Yeah see, the range of misty step is self, its effect is it moves you 30 feet. I don't think where you cast it from would change the effect to a 90 foot teleport. Check the scribe mage manifest mind discussions for the arguments I guess. a lot of people agree with the increases misty step range argument. I don't.

 I was thinking about this: Doesn't a touch spell like Vampiric Touch or Shocking Grasp require you to hit the victim with your physical hand? Similarly to how True Strike requires you to hit the target with your physical weapon? If the electric damage of Shocking Grasp is channeled/tranfered why not the radiant one of True Strike Strike as well? Your hand is not there with the GoTM target the same way as your weapon is not. 🤔

Even if those spells do require touching the target, the creature you're using Gaze of Two Minds on can touch the target with their hand. But the GoTM creature can't hit the target with a weapon that's in your hand, and the weapon has to be in your hand to cast True Strike.

But is the touch from the GotM "host" even required?

Because if it isn't.. I kinda think True Strike should work.

The only thing the rules say is that you count as being in the same square, so to speak. Like being in 2 places at the same time just for the purpose of casting. I don't think the host has to do anything at all. He could even be touching another target.

The issue with true strike is it is attacking with an actual weapon so if I'm in room A with a sword my familiar is in room B And I cast through my familiar true strike, well my sword is still in my hand so I can only attack something within 5 feet of me.

 I completely get it, my point is (and I might be wrong of course).. isn't Shocking Grasp also requiring an attack with your actual hand?

Then all touch spells would not work, because your hand is not where your familiar is, same way as your true strike weapon (the spell component) is not. 

While perceiving through the other creature's senses, you benefit from any special senses possessed by that creature, and you can cast spells as if you were in your space or the other creature's space if the two of you are within 60 feet of each other.

For all the purposes of attacking, you are considered in the same space of the familiar, so if someone is 5 ft from them, they are from you and your radiant weapon of light. 

It is such cool setup for an assassination. An ally could be next to the target but speaking to someone else, and a slash of radiant energy might suddenly appear and cut down the victim. 

No, shocking grasp is more like a firebolt but with a range of touch. The target is the person you touch. With true strike the target is your weapon. That imo is the distinction, not the range but the target. Which mechanically is the range. 1 is range self the other is range touch. range self wont work like that, range touch does. But thematically and why one makes sense the other doesn't is the target not the range. With true strike your target is your weapon which then attacks. With shocking grasp your target is whatever gets zapped with the spell. Now personally I'd allow true strike in he case where whoever you are gazing through was wielding a weapon. But that is more a rule of cool ruling than a logical one.

 But target and range are different things right? There is no indication on True Strike that the target is the weapon.

The weapon is just the material component from what I understand, not the target. The target is the creature you intend to hit. 

It also makes sense tematically: it is a Divination spell, designed to aim and hit a target through a single burst of magical insight, not a Transmutation spell like Elemental Weapon, Magic Weapon or Shillelagh that is aimed at the weapon itself.

 Here is where my interpretation differs: by this logic, whoever ally you are gazing through, if the warlock wants to cast shocking grasp, will also have to reach with his hand and hit. In my understanding, none of this is necessary. The warlock is simply in 2 places at the same time, overimposed the GotM host, immaterial, invisible and intangible for every aspect except the casting of spells. 
What I would rule, for the sake of logic, is that a player or creature with True Sight would see his spirit overimposed the host though.
