Infusions that allow buffs
Only five listed infusion types retain the ability to receive spell or consumable buffs under the supplied upgrade guidance.
How it works
The upgrade passage says infusions adding any nonphysical damage or status effect remove the ability to buff a weapon with spells or consumables. It explicitly names Raw, Refined, Heavy, Sharp, and Hollow as the exceptions that allow buffing. It does not specify which individual spells or consumables apply to each weapon, or list every weapon's infusion eligibility.
Read the supporting references
Source-bounded reference to reinforcement, gem infusions, weapon skills, and boss-soul transposition described in the supplied Dark Souls III passages. It records documented effects and restrictions, not comparative effectiveness. Guidance explains the referenced mechanics; it is not a tested damage ranking. Check the stated edition and source version before applying a patch-specific detail.
