Haste and spell casting - how does it work?

[Fevelle]

Yeah I;m gonna have to go with Spellcasting and the Chipmunks here. Though I wonder about Swiftcast though. Haste, Presence of Mind, Fey Wind and Arrow can help speed up the voice, but Swiftcast makes the spell instantaneous. How does that work with speech?

Probably by removing the need to chant anything, so the user can channel the spell right away.

This would be my guess. To force-cast the spell without any incantation takes significant mental focus, so it can only be done periodically. Certain other spells are simple enough that they can be canted instantly without the mental buildup, like Aero and Scathe, but the tradeoff is that they are not very powerful.
