Verbal Spellcasting is a new system im development allowing players to get a new look and feel to sorcery ingame.
Utilizing their voices, and instantaneous Playertool feats, players will be able to perform spells, and rituals to great effect.
Spells, Rituals and the like, will be obtanable and researchable in-game from tomes, grimoires etc. But these are not necessarilly needed, in order to perform the incantation. However, the grimoires may hold clues and details explaining how to perform rituals. For all you know, certain actions may need to be undertaken, else the spell could back-fire.
