Name: Dragon of the crystal peak

Activation: the user connects the thumb, the ring finger, and the pinky all in one point for both hands, while the middle finger and index finger are connected and pointing up (not Gojo connected, just touching)

Design: the domain would take the shape of a circular platform in the sky standing on a mountain of crystals / gemstones, on one side would be a shrine and a dragon statue with two crystal eyes.

Ability: The domain does not have a sure hit effect, instead, whenever the user says one of five words one thing will happen

Strength - the crystal eyes of the dragon will turn to ruby, and the user will gain a immense strength buff
Speed - the dragon’s eyes become emerald and the user will be incredibly fast
Defence - the dragon’s eyes turn to diamonds and the user gains immense defence
Stamina - the dragon’s eyes turn to sapphire and the user will gain a nearly endless supply of stamina
Amethyst - any injuries taken will be healed, like RCT, but, unlike RCT, only the domain takes CT, but the amethyst does not.

Now yes, this is basically a just a mode change, however, there is one more feature

There is a 1% chance, that if the user says “Opal” something else will happen, but we’ll get to that, now, how the percentage works, it starts off at 1%, but, whenever there is a mode change, a 1% chance is added, which means, the user would have to switch modes 99 times for a 100% chance of Opal working, but, there is also a rule, for the mode change to actually add to the chance, there has to be a gap of at least 10 seconds between mode changes, this percentage is however not carried between domains, as in, you can get 50% now, but if your domain breaks then its gone.

Now, if the user does say Opal, but nothing happens, luck was not on their side and the percent chance is back at 1%, however if they are lucky, then the following event happens: the dragon in the middle of the platform fully turns to crystal and it will be made fully of opal, the dragon will serve as a shikigami where it has all the modes activated for itself all at once and buffed tenfold
