For Every Action ...

Basic Fantasy RPG does a good job translating many old-school mechanics into a standardized d20 system that modern role-players tend to find more intuitive. Yet, there are some rolls it keeps as 2d6 like reaction and morale.

However, adding standardized ability bonuses to a 2d6 reaction roll weights the impact of the ability too heavily. Old-school games tend to cap the impact of Charisma on a reaction roll at +2. BFRPG maxes out at +3. 5th Edition takes you to +4 and possibly beyond.

I like reaction rolls but my current games use the 5th Edition rules at their core, so I took Knave's reaction roll table and pasted it on a d20 scale so that PCs could apply their Charisma bonus.

d20 Roll	% Chance	Outcome	% Chance	2d6 Roll
1	5%	Hostile	3%	2
2 - 6	25%	Unfriendly	25%	3 - 5
7 - 14	40%	Unsure	44%	6 - 8
15 - 19	25%	Talkative	25%	9 - 11
20	5%	Helpful	3%	12
