[Renewal] SBK Gx in renewal

[barragazz]

hi fells a bit confused with renewal SBK / Soul destroyer formula.

the one i know = Pre renewal = ATK + INT
but i look up at IRO Renewal website it says = ATK + MATK,

so in renewal SBK / SD GX is based on ATK + MATK is it true? or someone can verify this?

thanks in advance
