Você só precisa configurar aqui:

bstor = 17824 -- Storage do boost
percent = 20 -- Quantos por cento a vida do summon aumentará ao receber o Boost
maxboost = 50 -- Level máximo de boosting

E aqui:

<action itemid="6310" allowfaruse="1" event="script"><!--[CDATA[

No lugar de 6310, você coloca o ID do seu item de Boost.

E se souber o que está fazendo, pode também editar a fórmula do dano extra do boost:

local dmg = math.floor(value*(getBoostingLevel(attacker)/10+1))

Boosting:
