(11:27:58 PM) Uhoh. There’s no key bound to action ‘Switch to Hotbar 3’.
Any idea what this is for?
This message indicates that you’re missing an important keybind in the game settings.
You can find it under Keybind -> System -> Switch to Hotbar 3.
Please take a look at this guide for detailed information: Keybinds and Icons Recognition
and for the SCH question does it heal NPC’s? (mainly for certain dungeons where you gotta keep them alive)
Miqobot heals party members only.
If you are in a dungeon with Squadron or Trust NPCs, then yes, Miqobot will target and heal them.
If you are in a duty without a party, then no, they will be ignored.
also the sacred soil macro would just be a /cast sacred soil macro right?
Here is an example of placement macro for Sacred Soil:
/micon "Sacred Soil"
/merror off
/ac "Sacred Soil" <t>
/ac "Sacred Soil" <me>
You can find detailed explanation of placement macros and how to create them in the main combat thread:
