Doing spelguru's gravity reversal would be too tricky as a test spell... instead... well, this took like 2-3 minutes. The editors seemed straight-forward enough... which means nothing since I wrote them... let's see... a few things might need clarification, but anyway, here is the test case... hopefully it won't ever be released:
------------------------
Spell Template: Detonate Body Part
2 steps:
1)Target Body Part
2)Detonate Target from step #1
----------------------
Magic Art: Detonatology
Has 2 Basic Effects
1)Blast Part (detonate type effect)
2)Acquire Part (target type effect)
Has 2 Effect Skills
1)Blastology tied to Blast Part
2)Body Focus tied to Acquire Part
Has 2 Power Sources
1)Blast Suck (drains blood)
-- used by Blastology, is also skill
2)Blast Drain (drains energy)
-- used by Body Focus, not a skill
Has 1 Spell
1) Splatterification
-- tied to Detonate Body Part Spell Template
-- ties Body Focus and Blastology to
the two spell template steps, respectively
Has 1 Spell Skill
1) Splatter Weaving
-- tied to Splatterification
-------------------------
I guess I said I would use UBB to make my posts nicer. Oh well. Anyway, when my test player actually has these skills, it won't be so convoluted. The player will just run around screaming "I want to Splatter Weave!!!" and pick targets. There will be lots of skill increases and so on, but the player need not pay attention to that. None of the effect names, etc., will matter unless you want to make custom spells. Effect skills may be marked "freeform", meaning that they can be used in custom spells. Detonatology has no freeform effects, because, well, there are no options there. Freeform arts will be more like, well, a lot of magic from different places... where the caster can just do the effects he or she knows. An art with no freeform effects is stuck with a list of set spells, more like traditional DND or whatever. Freeform is more versatile, but requires more out of the player.
