element="Wind, Fire"
Didn't register for either of
Code:
<if element="Wind">
<command>echo Element=Wind</command>
</if>
<if element="Fire">
<command>echo Element=Fire</command>
</if>
So the easy way is out.
However, spellcast supports at least some regex:
Code:
<if advanced='(bool)regex("%SpellElement", ".*Wind.*")'>
<command>echo regex Element=Wind</command>
</if>
<if advanced='(bool)regex("%SpellElement", ".*Fire.*")'>
<command>echo regex Element=Fire</command>
</if>
Both registered matches - Given that the element field is never used otherwise, it'd be possible to cram it all, wselement for obis and skillchain properties for mekira oto/athos gloves in there - downside writing the rule for it isn't something I'd expect just anyone to be able to do.
There really isn't as many weaponskills to add to the magical list as I had thought, I'll make an update with simple element="Dark" for cataclysm/etc.
Also possible to enter the skillchain information in say.. recast, but would need to be as a number. Definitely could be done (0 = none, 1 = fire, 2=wind, 3=(fire and wind), etc) but would end up being fairly arcane.
