Look less to the runic item slots and look more to what Mathilde has to work with:
-Around Mathilde - Mathilde needs this space free of Wind magic, permanent Runic magic is okay, permanent Wind magic is okay IF its made by Mathilde.
--Belt
--Aethyric Armor(her own, so it doesn't disrupt her spells)
--Her spells
--Potential runic banner
-Inside Mathilde - Mathilde this space free of any permanent magic unless it can be easily turned off for spellcasting, is fully in tune with her own magic, or only activates for short periods.
--Her spells
--Potentially Mathilde-crafted Talismans
--The Seed
-Applied By Mathilde to Target - This has no limitations other than Mathilde's ability to physically carry stuff and be able to equip them in a hurry
--Sword
--Staff
--Grounding Rod
--Pistol
Carrying a flagpole would seem to interfere with quite a lot of stuff...
