I was able to speak to a couple of players from my play group who went to a regional and I got a disturbing report about a possible dice manipulation that I will share here.
I would like to say first off is that I was not present to witness the described behaviour and I am getting this all second hand so bear that in mind.
The juggler's dice ability was described as this:
" The player would place the dice in his hand (just off of the table surface) and he would adjust his hand to allow them to roll and adjust in his palm until the dice were in a specific orientation. He would then quickly turn over his hand so that the dice would rotate 1 to 1 1/2 times and land showing hits. He was disproportional generating hits for his squad."
The players found out when they talked in the parking lot (either at break or after the regional when they could talk about their games) because he was generating consistent hits across his games, without any modifying what so ever (or none needed).
It was said that the dice the person was using had a dot on one surface that he wanted to have face up in his palm. (Some did not see this so are unsure if there was a dot or not)
There are two parts to this but I would like to discuss option 1 more.
1. Just the technique of flip-handing the dice - legal/ethics?
2. Spot on dice - illegal for sure as it is not standard equipment from the core set. Pretty obvious but the players weren't 100% sure that they were marked, just how he rolled the dice was what came across more.
If you play across from this how would you proceed after seeing it done?
P.S. I won't release details regarding who was suspected of this behaviour. I've kept it more to the behaviour in question than an outing of the person.
