   • Spellcasting GUI
4. Implement spell skill system

Special IDs

Special IDs have to cover magic, weapon-based special attacks and other applications for the special systems (emotes?). They are 32bit long. The first 2 bits decide if it is a spell, physical attack move or something else. How the other applications of the special system use the remaining 30 bit is up to them. Here is how the magic system is going to use them:

 0 -- This is a spell and not something else (4 possible)
 1 -
 2 -- application syllable (64 possibilities, 45 in reserve)
 3 -
 4 -
 5 -
 6 -
 7 -
 8 -- effect syllable element (16 possibilities, 8 in reserve)
 9 -
10 -
11 -
12 -- effect syllable power level (16 possibilities, 12 in reserve)
13 -
14 -
15 -
16 -- enhancement syllables bitfield (16 bool values, 9 in reserve)

Healing spells use different application syllables than attack spells, the element bits are ignored for them and the power level bits are used as-is. Most of the current enhancement syllables don't make sense for healing spells, but I could imagine some new enhancements which do make sense in this context. Maybe we can use these 16 bits for healing-specific enhancements which have a different meanings than the offensive enhancements which use the same bits.
