SSEdit/Creation Kit: NPC won't use staves in inventory

[UselessAffro]

Hi, I am making a Brand New Shei, but he won't use his custom staff.

I tried:

• Setting the damage to a high value so the NPC chose the higher damage item. 
• setting a combat style to csHumanMage or csSpellSword and with any of those the staves have higher priority than melee but he still does not use it.
• changed the class from Vendor to CombatMageConjurer and that still would not do it.
• created a new CombatStyle just to test it creating a much higher proficiency to use staves and still no use of the staff.

I am testing with a dummy Staff, in this case, summon Familiar.

What am I missing? The mod is already uploaded but is still missing this basic feature.

 

Thanks for your time.

Ash Guardians require a heartstone, at least when the summon spell is used, not sure about using the staff. Have you tried giving your NPC a heartstone?

This staff works fine without the use of Heartstones (which is quite unbalanced indeed) I have tried the staff in my own character, however, I stated in the first post that the test was also done with a Staff of Conjure Familiar, and still does not use it.

Please do request any further info or screenshot.

For me, this does not make any sense.

I have always given staves to a lot of NPCs in-game and they tend to use them even when they are melee but Brand Shei totally refuses to do so even when I changed so many aspects.
