heres what i came up with on spellcast.
Code
<if advanced='"$autoMB" == "1"'> <if spell="Boost"> <command when="aftercast">input /ja "Immanence;wait 1;input /ma "Fire4" <t>; wait 9;input /ja "Immanence;wait 1;input /ma "Thunder" <t>; wait 5.5;input /ma "Fire5" <t></command> </if> </if>
This worked fairly well for me sch/rdm, loquacious, af1 feet, and acp body. Was working out timings while working on my tom staff. Used job ability for dummy spell because I didn't want one with a huge delay, since the mob might be slept or gravity. As for if you get +2 set proc sol i guess?
edit: and make sure to change the <t>; in the code to < ;t> ;; (no spaces before semicolons)
