If I'm gonna be testing a level 20 enchanter tier 3 archmage against, say, Treerazer then I'll need to know how many mythic points I can spend in a round. Here's what I know.
• Add 1d6 to d20 roll just made: immediate action (p.4).
• Bonus turn from amazing initiative: free action (p.6)
• Arcane surge, wild arcana, mythic spells: unknown (p.7, 27)
Is there a default assumption whenever a type of action isn't made explicit?
I would assume you merely spend the point as part of the secondary action (ie - casting a spell). The same seems to be true when casting greater mythic spells
The wording is different from the path power Channel Power which IS part of casting a spell.
Secondly it goes against the pattern maintained by all the rest of the paths - their 1st level ability is always either a swift or immediate action - if these abilities (and the Hierophant's equivalents) aren't treated as swift action. In general, I noticed that every path gives a way for that character to gain an extra attack or spell (or extra move and attack as the case maybe) for either themselves or an ally.
I'd say these are meant to be swift actions.
Another arcane surge question: when you use arcane surge to cast a spell, is that spell expended? I'm 90% it isn't, especially because you can use surge to cast a spell you have prepared and already cast. I would just have expected it to outright state that "the prepared spell or spell slot is not expended when casting with arcane surge."
You still have to cast the spell. It's just that you use your ability as part of the action to cast it, rather than as a separate action of any type.
But doesn't spending mythic power let me cast extra spells in a turn (or is that round)? I'm still confused and I'm really hoping Jason clears up any ambiguity.
