Doppel Weapon-Switching. Current negative aspects of the mod (system as a whole, not minor bugs): 1) You have to necessarily interrupt the action of the clone (excluding the summoning version). 2) You have to necessarily switch weapons with Vergil. 3) You have to necessarily do something to force models to change (simply switching to another weapon in the HUD is not enough). A JC, landing, moving, starting a move with the new weapon accelerate this, but again, it's imposed. Usually you can't simply switch weapons passively (HUD), switch doppel's weapons, and then continue with Vergil without having used that weapon at all. 4) You will necessarily change the position of the clone, forcing him to come to you. 5) If you switch weapons with Vergil and ONLY want the clone to move where Vergil was without using JFJCs, calling him will force a not necessarily desired weapon switch for the clone. And there are many instances where you either don't want a JFJC, or you can't

Judgment Cut System Mechanics and techniques (at least what's known to this date) have changed quite a bit from 4SE . They aren't based on any glitch that happens regardless of the lapse of time holding melee anymore. This time techniques are based precisely on buffered charges, and all of them are subject to what I call for simplicity the Jackpot rule . In DMC5SE Vergil can perform up to 4 judgment cuts in a row (without any action in-between): [1 normal Judgment Cut + 3 Instant Judgment Cuts] Usually, after 3 Instant Judgment Cuts (with or without the normal one before), Vergil will say Jackpot , hence the name of the rule. But what does the rule mean? Speaking about aerial Judgment cuts, as long as a Jackpot is avoided , Vergil can intercalate a ground trick, air trick, trick up or air taunt between further series of Judgment Cuts (which will usually start with a normal one). For example, 1 ground trick Judgment Cut and 1 Instant Judgment Cut -> trick up -> Normal
