Changes the Latenna the Aubinauric Spirit Ashes to summon her and a large wolf. She should mount the wolf as soon as they appear.

Installation:
- Download Yapped Rune Bear (This was made using v1.10.1)
- Copy the .csv to the /res/GR/Data in Yapped's directory and overwrite
- Open your regulation.bin file in Yapped
- Go to BuddyParam on the left the tab, then Tools -> Import Data
- Go to NpcParam on the left the tab, then Tools -> Import Data
- Save
----------------------------------------------------------
Edited Params:
BuddyParam:
20400000 - Latenna the Aubinauric, edit -> duplicate row 
Set ID of duplicate row to 20400001, name it how you want (I used Latenna the Aubinauric for simplicity). 
Set NPC Param ID of 20400001 to 31800053, NPC Param Think ID to -1.
NpcParam:
Duplicate row 31800052 -> Set ID to 31800053, name it something like Dog Buddy. 
Edit 31800052's Team Type to 47 - Spirit Summon and SpEffect ID[29] to 297000.
OPTIONAL: set SpEffect ID[3] to 0 in NPC Param for your duplicated row to remove the scaling from Consecrated Snowfields. Otherwise, it will stack with the scaling from upgrading the Ashes and make the wolf stupid strong (1300-1500 damage per bite).

Thanks to poster Vinnihell for this info:

Edit these lines on your Dog Buddy NPC to make them look like spirits.
s32 SpEffect 21 - 10434
s32 SpEffect 24 - 5130
s32 SpEffect 26 - 4302
s32 SpEffect 27 - 295000
s32 SpEffect 28 - 296000
s32 SpEffect 29 - 297000
s32 SpEffect 30 - 152
s32 SpEffect 31 - 461

This will also make them look like ghost like the other spirits, not sure which one does that exactly

all credits to user Big Iron (for the dog thing) and Josko (for the summon appearance).

KNOWN ISSUES: 
If they spawn away from each other, Latenna can't mount, because the Wolf won't move.
