Example, to target heals on the character the boss (e.g. your target) has targeted or if that doesn't exist targeted at the FTL leader:

Code:
!if (character in "Monk" and character in "Healer") /castsequence  [@targettarget][@{FTL}][] reset=15 renewing mist, null
or for something you always want targeted at a particular slot or yourself if slot 1 doesn't exist:
Code:
!if (character in "Monk" and character in "Healer") /castsequence  [@{SLOT1}][] reset=15 renewing mist, null
