Publisher Description

d20 Attack Calculator is a powerful combat calculator, optimization tool, and dice roller for d20 RPG systems such as Pathfinder RPG or D&D 3.0 / 3.5. Use this program to roll dice for your complex attack routines and evaluate your character build from visual graphs and dice roll statistics.

* Plot key statistics for your dice rolls:
- Expected (average) damages
- Hit chances
