# Instructions
2+
3+
For a game of [Dungeons & Dragons][dnd], each player starts by generating a character they can play with.
4+
This character has, among other things, six abilities; strength, dexterity, constitution, intelligence, wisdom and charisma.
5+
These six abilities have scores that are determined randomly.
6+
You do this by rolling four 6-sided dice and record the sum of the largest three dice.
7+
You do this six times, once for each ability.
8+
9+
Your character's initial hitpoints are 10 + your character's constitution modifier.
10+
You find your character's constitution modifier by subtracting 10 from your character's constitution, divide by 2 and round down.
11+
12+
Write a random character generator that follows the rules above.
13+
14+
For example, the six throws of four dice may look like:
15+
16+
- 5, 3, 1, 6: You discard the 1 and sum 5 + 3 + 6 = 14, which you assign to strength.
17+
- 3, 2, 5, 3: You discard the 2 and sum 3 + 5 + 3 = 11, which you assign to dexterity.
18+
- 1, 1, 1, 1: You discard the 1 and sum 1 + 1 + 1 = 3, which you assign to constitution.
19+
- 2, 1, 6, 6: You discard the 1 and sum 2 + 6 + 6 = 14, which you assign to intelligence.
20+
- 3, 5, 3, 4: You discard the 3 and sum 5 + 3 + 4 = 12, which you assign to wisdom.
21+
- 6, 6, 6, 6: You discard the 6 and sum 6 + 6 + 6 = 18, which you assign to charisma.
22+
23+
Because constitution is 3, the constitution modifier is -4 and the hitpoints are 6.
24+
25+
## Notes
26+
27+
Most programming languages feature (pseudo-)random generators, but few programming languages are designed to roll dice.
28+
One such language is [Troll][troll].
