Description
The fade sphere shifts the user slightly out of the normal plane of existence, making them completely invulnerable and somewhat harder to see. However, they cannot cause harm to their foes. (invulerability, ghost, infinite ammo, nullified damage)

Definitely get a new sprite, but I really like the effect.

I wonder if I'll not be lazy tomorrow and mix something up.
We'll see.

That screen fade is too bright, IMO. You might want to tone it down a little.

And speaking of which, you can achieve that same fade effect in DECORATE with the use of A_SetBlend instead of using an ACS script.

Now, my gripe with the item, unfortunately, is the way it balances itself out; the inability to cause any damage, which in my book as a player even more important than being invulnerable and/or invisible. It's like giving me a new heart and taking away my lungs in return (probably a bad metaphor, but still, you get the idea).

I like the idea of it if it was an inventory item (Heretic/Hexen style), rather than a sphere. As an instant-use item, it's basically the mapper dictating "okay, for this section, you aren't allowed to do this" (which is a form of flow control that wouldn't be very popular among players). If it was an inventory item, it would be a get-out-of-jail-free card. I can think of a few occasions in several megawads where I'd LOVE the opportunity to become invulnerable temporarily just so I could run to a better position, and the inability to damage during this time would be an interesting balancer.

Well, if that's the case then this might as well be turned into a Doom styled Chaos Device.

Alright, mixed something up just now:


And here are the frames.
Animation is 4 tics for all but the last two frames, which last 5 tics.
No offsets, but SLADE3's automatic offsets oughta do the job easily.

I had actually originally intended for it to be a raven-style inventory item, but I couldn't find sprites that fit in at all.

Anyway, updated:
- Screen blend effect lasts for the duration of the powerup, but is much less intense
- Added blox's new sprites
- Changed to raven-style inventory item

Something about the sprite i dont like =/

All other spheres have some "edge" to them, a limit showing the outside of the sphere.
Bloax made a nice sphere, but it lacks some inspiration and that edge i refered to. it seems more of a creepy looking projectile or monster, hidden in a cloud of darkness.

The sprite's simply not Doom-style. Turning it into something that looks like a mix between this and the Soulsphere and I am fine
