Hi there Werby,
Thank you for enjoying the game, the Pidgin is one of my favourite little pieces in the game. We've been looking at this trick to clear up some points in clarity for the next update.
To answer your question, the dice distribution should be as follows.
Point 2: The lingua has 3 dice on creation.
Point 3: The lingua should have 4 dice (it gains an additional dice for this point of the trick tree)
Point 4: The lingua now has 5 dice and has the additional abilities from synonymous.
Hope this clears things up.
Join our discord if you get the chance, we'd love to hear about your adventures so far. The link should be on the inside cover of the book :)
If not, good luck on your game
