Blinded and cone shaped spells, can it still be done?

[Chyrone]

Hello everyone,

Something's come up and i need to be sure of something.

Baddie gets glitterdust blinded (always good).
Said baddie casts a cone shape spell, no targets required, point of origin: himself.

A player suggest this to be impossible. Player calls from the CRB; pg. 214 states

"Regardless of the shape of the area, you select the point where the spell originates, but otherwise you don't control which creatures or objects the spell affects. The point of origin of a spell is always a grid intersection."

While i am aware of specific target spells are a no-go, such as disintegrate and create pit/grease, i have some doubts whether the above objection applies to the baddie's spell, which originates from himself.

(which another player says is possible)

Thus, can it be done or not?

Thanks in advance,

Read a little farther and you get:

Cone, Cylinder, Line, or Sphere wrote:

A cone-shaped spell shoots away from you in a quarter-circle in the direction you designate. It starts from any corner of your square and widens out as it goes. Most cones are either bursts or emanations (see above), and thus won't go around corners.

All that's required to target a cone is that they can pick a corner of their square and designate a direction. None of that requires sight.

While we're here, create pit should work fine if I'm not missing anything, provided you either blindly pick the spell direction and distance (point to a square) and roll miss chance to see if you manage to tag the target or fail the spell, or far easier cast it on the ground and it'll either be or not be in a useful place.

can you cast spells while blinded? Yes.
see the condition Blinded. The home GM may impose some spell failure similar to being deafened if you have to drawn sigils or figures.

As stated by another poster the caster chooses a grid intersection (corner of his square) and then direction. The spell Area of Effect is determined from that origin and direction.
