Hi Christopher. Saves only show what the character has as a base according to their class/level and any misc adjustments (racial, class, gear, etc.) The roll will show a success/fail only vs that adjusted base. Each roll includes a query that can adjust the roll +/- which can accommodate circumstances requiring the roll. The DM decides what the actual threshold for success is and can rule accordingly. Attacks only roll a d20 plus mods. It is up to the DM to decide if the attack roll was a hit or not given the players do not know the AC of their foes. The Attack Matrix (or THAC0 ) vs AC table is only shown to the GM as a whisper in chat with the attack. Cheers
