The Royalguard style is one of the more difficult styles to master, but potentially one of the strongest. When the Rage meter is full, Release and Just Release are two of the most powerful known moves in the third and fourth games. The moves' power are enough to kill almost all kinds of lesser demons in the two games. Though it is time-consuming to fill up the meter, the usage of Super Costumes can help (which provides infinite Rage meter). Furthermore, in Devil May Cry 4, a maxed-out Release can remove the electrical shield of a Blitz without even absorbing any backfire damage.
In Devil May Cry 3, the amount of pent up power is signified by the jewel-like dots on the display bar. Dante's next strike will be increased in power by about 2% for every gem lit up. Effective for the next blow only, once per charge, acting similarly to Nero's Exceed system.
Release all the anger stored within you as a violent, damaging counter-attack against those unfortunate enough to provoke you.
A mysterious technique that transforms the body into a seemingly metallic shell impervious to enemy assault. The duration of the technique is linked to the amount of energy stored within the Royal Gauge.
A small visual glitch involving the Dreadnaught Form allows the player to use the Dreadnaught model and its audio clips while being able to move normally and taking damage as usual. In order to utilize this glitch, the player must switch their weapons precisely at the moment when Dante changes back from using it.
Dante's release in DMC 4 has different effects based on the meter. For example, an empty meter will release a rather small and weak light. A filled meter will have stronger light, where a 3/4 or full meter will have strongest light with vibrating screen. And a full gauge royal release will cause some extra electric-like sound.
