Effect: The user faces his palm upwards and creates a golden circle. However, the spell has no initial effect since this is a chain spell. The spell upon casting will only activate if a ball from Light initiation was activated. If this is the last Judgement used then the one who touched the ball and the user's position will exchange, with the permission from the other player and the user. If both players who touched agreed their current position switches. If the user touched the ball instead, then he will just stay in place and the ball will just disappear.

Effect: The activation works like the Light Judgement I(Trade). Like that spell it is also a chain spell meaning it won't have an initial effect. This spell's effect is when a user touches the ball while this spell was the last cast judgement, then the ball will explode sending out coins everywhere. The coins are not normal coins the coins upon explosion would damage the enemy who touched the ball. The coins can cause minor bruises on impact. There are 5 coins exploding on all directions making it harder to dodge. The damage of all five coins are equal to a D-rank damage. The explosion does not deal any damage, only the coins.

Effect: The user upon activation faces his palm forwards and create a golden circle in front of his palm. The user will release a force that can push an enemy backwards that can cause bruises if they are hit directly. This skill can also be used on light's initation ball pushing the ball forward without activating it. The distance a ball can travel is 5 meters.

Alright, I'll be taking a look over these!

Mercury's Cunning - The rules for sustained spells have changed since your departure and return. They can be found in the buffing rules, but sustains are no longer a thing. You may only have a spell active for a time period based off rank of the spell. Please check for the exact numbers.

Light Initiation - Again, there is only a set amount of posts for 'sustainability' based by ranks. I believe D is only two posts.

Light Judgement I (Trade) - This causes loss of control of one's character, which falls under God Modding. Please fix.

Light Judgement II (Thief) - 20 coins is far too much for a D Rank spell. I'd allow five, maybe. As a D Rank the magic is still weak, and effectively you're still learning. 20 coins would have to be for an S Rank at least (with split damage). Please state that all 5 coins (if that's the amount you use) have to connect for the full D rank damage. Also state that the explosion does no damage.

Light's Travel - Approved.

Changes :
Fix the sustain , c = 3
d = 2

Trade skill requires permission of the other player to switch place.

changed to five coins noted that in total 5 coins = d-rank damage, and the explosion causes no damage

Mercury's Cunning - Lower the Cooldown to 3 posts. This Cooldown starts after Cunning Fades.

Light Initiation - D Ranks can have a cooldown of 1, which starts after the balls are used or fade. Also, you mentioned balls, as in plural. Please give a static amount.

Light Judgement I (Trade) - Approved.

Light Judgement II (Thief) - Approved.

Bump when edited.
