Note: The following triggers only matters for the pony version.

Base trigger word is "magnaluna"

"pony" - Regular ponies

"anthro pony" - They have hands

"furry" - Everything else

Use "luna" and "celestia" by themselves without princess for MagnaLuna style bias, include princess to decrease bias

This Lora also (somewhat) understands different Luna versions;

luna + white hair

luna + purple hair

luna + dark purple hair

luna + blue hair

I recommend a lower strength for vague or less specific prompts, otherwise 0.8-1 is good.
