How do i make a system that allows to switch abilities packs

[SetaSouji]

ermh, its like this

PERSONA is a creature that contains spells and abilities
a SPELL BOOK that contains a PERSONAS , and if the player clicks the PERSONA icon and a monster will spawn then disappear so as a prove it has changed personas
and after changing personas, the player's hero will gain a SPELL BOOK that contains the PERSONA's ABILITIES .. so how do i make it.


i know how indeed, but how do i make the personas abilities? coz if the player keeps switching personas, how do i make the variable i created to remember the abilities remember them all

aaa confusing!
