Could you please provide a bit more detail on how skill/spell cooldowns are going to factor into the games combat system?
Sure, let me give some specifics on how we are planning to incorporate cooldowns into the wizard class. First off, cooldowns are NOT on individual spells. For any particular spell, you cast it, and when you are done, you can cast it again right away. But one limitation is on spells of a particular level. When you cast a certain number of those spells, in any combination, then the whole spell level group goes into a cooldown, and you can't use any of them until that cooldown has passed. That cooldown is long enough that for short battles, you are limited to casting a certain number of spells for each spell level. For long battles, that cooldown might expire and you can start casting those spells again.
The other cooldown has to do with your grimoire. A wizard may know a lot of spells, but he can only cast a few basic spells plus the ones that are in the grimoire that he is holding. Grimoires vary in size, holding various numbers of spells of different spell levels, and the player is free to load up his different grimoires with spell combinations of his choice. But once combat begins, switching grimoires causes a cooldown for all of those spells, leaving the caster only able to cast his basic spells until the grimoire cooldown passes. This means the player will have to think carefully about which spells he adds to a grimoire and under what situations he would want to switch one for another.
