'what involves spells' is the definition.
I can't tell whether this definition defines the answer.

'tungsten-tipped long vessel' is the wordplay.
'tungsten' becomes 'W' (W is the chemical symbol for tungsten).
'tipped long' becomes 'itch' (I am not sure about this - if you are sure you should believe this answer much more).
'vessel' becomes 'craft' (synonyms).
'w'+'itch'+'craft'='WITCHCRAFT'

'in' is the link.

Can you help me to learn more?
