I have these on my main SCH hotbar: Adlo/Embrace combo, Physick/Embrace combo, Adlo by itself and Physick by itself. The latter two are because I don't want Eos/Selene to always be locked to my GCD healing the same target- like if I'm always doing Physick/Embrace on the tank (or the Adlo version), that means Eos can't heal someone else in a situation where we'd ideally be healing two party members at once (like me casting Physick/Adlo on the tank while the fairy heals a DPS if they both took damage). WHM's have stronger AOE heals than we do so getting in a situation where we have to heal everyone one at a time from low HP can be risky if the fairy is locked to the same target as us. But it does have its benefits (extra strong single target heals) when we need it, so I keep both options on the crossbar, and there's one other scenario in which I use the combined Physick/Embrace combo that's super helpful- healing while dodging.
If I'm having to heal on the run, I'll hit the button for my Physick/Embrace combo and Physick will cancel out because of me running, but Embrace will still go off if Eos/Selene is still in range of the target since she doesn't move until you move a certain distance. You can practice this out by casting it on someone while running in circles around them- Physick doesn't go off, but Embrace does (and at a cost of 0 MP). While I could accomplish this with Embrace set to its own spot on my crossbar, space is already at a premium for SCH as it is and this accomplishes what I want it to, and is useful in multiple scenarios:
Macro Code:
/micon "Physick"
/ac "Physick" <t>
/pac "Embrace" <t>
When Physick alone is sufficient of course, that's what I use. And on the really rare occasion I have an MP problem and want a free heal cast I'll use this, and cancel the Physick part to use the free-MP Embrace cast instead.
