I have done a few times but I cannot catch the pattern/trigger criteria of a particular Longsword combo.
By using R2+Triangle I will perform a stab, occasionally a follow up combo will occur where I will jump up and slash back down dealing multiple small damage, I find this move very useful but lack the ability to actively trigger it.
So far I only noticed a red glow during the stab which causes the jump slash but no hint of what triggers the glow. I have confirmed that having maxed Spirit does not guarantee the combo, though it seems to happen only with maxed Spirit(my observation might be wrong).
How do I trigger that jump slash after the R2+Triangle stab?
