How would you run a blind summoner as a GM?

[Ravingdork]

A summoner without any particular extrasensory perception abilities is fighting in a melee duel. In the dark. Don't ask why. For the purposes of this example, he just is.

Nearby, in the same room, is his eidolon. Unlike the summoner, the eidolon can see in the dark and is observing the duel as it takes place. The summoner wants to use his eidolon's sense as his own, so that he can see in the dark and fight.

How would you, as a GM, run this? Would the summoner take penalties? Would you say the action cost for Share Senses is enough? What might you do if a player requested this of you?

What if it was something more benign, like the summoner and eidolon walking together down a dark corridor? Would you treat the summoner as blind, even if he was using the vision of the eidolon standing right next to or just behind him?

If there is an action cost, I would say it is a high enough price to pay. The Summoner and their Eidolon have had all the time they need to learn and work in tandem.

Also it makes for a fantastic backstory IMO.

I had a recent similar scenario where the players had stolen the head of a skeleton they were fighting. I gave them Clumsy = the spaces between the head and the body (up to 3.)

The eidolon is viewing the fight from a different angle (3-person)
If the summoner uses the eidolons senses he would have to compensate a lot.
Some miss chance would be appropriate perhaps just give the fighter consealment.
If you wish to be harder then make the summoner flatfooted.
Why isn’t the summoner casting light?

Well, also why isn't the eidolon helping, and why isn't the summoner unmanifest + manifest.

Would be always better to expend 2 rounds to get the eidolon next to him rather than using 1 action to see through his eyes and the other 2 to cast a cantrip.

Anyway, given a situation where the summoner has to fight in the dark and the eidolon can't help him ( and also cannot be summoned next to him ), I'd give the summoner the possibility to use the eidolon sight, but since it's from a different angle ( as *Khan* already mentioned ) I'd give some circumstance malus ( -2 for example ) on hit.

Familiar conduit allows you to cast a spell that originates from your familiar with no penalty, even if it is an attack roll spell. I think it fair that the Summoner in such a similar case would not suffer from a penalty either.

The difference would then be using "also" the familiar position ( conduit familiar ) vs using "only" the familiar position to see the enemy that a spell, or attack, is about to hit from your body ( which you can't feel anymore if not by sight from the eidolon position ).
