Truane's Star Expeditionary Service
Percentage Based System
D100, D10 and D5
The game system uses just the percentage and 10 sided dice throughout the game. The entire game system is based on a 1-100 based rolling system for skill checks, combat, etc. You also roll D10 for certain things (like Initiative) and D5 on very rare occasions.
Roll Low / Critical Success / Failures
The skill / combat section is all about rolling low. 01 being the best roll of the game while 00 is the absolute worse (when it comes to skill / combat checks). Based on your skill level determines the chance of a critical success . For example:
Level 3 BEAM Weapons Skill (50% chance to hit) =
01-08: Critical Success or Hit (5+3%)
09-50: Success or Hit
51-94: Failure or Miss
95-00: Critical Failure or Critical Miss
At this time Roll 20 doesn’t allow formulas for Critical Hit / Miss. Critical Hits will be at the default 01-05 in system.
