I would set aside the exact number of dice before my turn, color dice coded per attack type.
I only even had dice applicable to the character. There was no die hunt
I was optimized.
So I would pre-poke the people I wanted to grant attacks to so they could be prepared to do a basic attack too.
BUT I WAS NOW TIMING EVERYONE'S TURNS. Guess what, I was the fastest player at the table despite having the most complicated turns.
I think it was because I let everyone shine and stole his thunder, IDK.
I never called him out, I just stopped playing anything with him.
I wish I would have been able to finish the EPIC chain, but meh.
AND HE WAS DOING THE SAME THING TO ME.
Listen fucker, I have a legit level 9 warlock, i know how to play her.
He cheated and just made a level 7 fighter at the table. I'm like WTF
And he certainly wasn't telling the other 2 dudes how to play.
And his daughter seemed to have a better handle on her class than he did (a sorcerer)
And me and the daughter were basically sitting there feeling oppressed together.
She would shoot me sympathetic looks, and I would do the same to her.
If it's me and five white dudes, I'm probably going to have a bad time.
That's my decades worth of experience with OP.
And I have so many online video game stories it's too much to list.
It always comes down to "Do I love the game enough that I am wiling to put up with toxicity I may encounter"
