Once with Seromet I did this emote...
emote flicks his hand suddenly towards the priest, the gesture brutally flinging the man against the far wall.
After which I landed a critical FoD to stun on Mezcao. That was pretty cool.
So, I can see the "flips out and rips you in half" thing being done...if you know it can be done. Like Slayne cleaving a naked journeyman if provoked. I bet he really could flip out and rip them in half.
I always do emotes like that. If it's a mage they usually have telekinesis and can lift things from drawers or slam doors without touching them.
When Satomi and I did RP to take away her leadership it was all post PK magic emoting. I set her corpse on fire with the Maidens corrosive greeny goodness. To which I'd emoted it showed her in the corrupted, aged look that the Maidens fire is RPed to be.
With Renidius I had aliases for spells. Holy word sent spears of light lancing out from him, bolt of glory was a kamehameha kinda blast, flamestrike was him rasing his hand and calling starlight from the heavens (yup even during the day!). There was probably more...
So I think it can work in PK situations aswell. It just adds more flavor.
I remember that clown of Meissa when I played Abdar, Benzo. That guy was the shtuff. He'd just manifest it and balance on it or something.
Besides the little stuff of shielding yourself from rain, if you ARE an all powerfull wizard or a HF of a faith you can go abit farther. Like summoning unholy fire to burn around you, or shining light to envelope you.
Hell, with Seromet I logged out with a...
pemote form falls apart into a multitude of insects, maggots, and other vile vermin which at once scurry towards the shadows.
...I also had me a Throne of PEstilance due to emotes. These things were more RPable because of Thuban's robes of kick-assery that I had.
edit: Falicis also used to sit on ceilings. Thats cause he was a vampire
