Travel speed: 1 mile/action
Duration: 1 melee round per level
Range: up to 100 miles with little difficulty, but theoretically thousands of miles if the connection is there.
Navigation: Traveling a distance greater than 100 miles (160 km) requires line
navigation - Base Skill: 55% +4% per level experience (-5% penalty for every 300 miles/480 km of distance). A failed roll means the character emerges 3-18 miles (4.8 to 29 km) from his target location (roll 3D6 to determine the distance).
These 4 things do not seem to add up: Even given a character with 10 attacks a round, it would take him getting to 10th level before he could POSSIBLY go 100 miles, based on limits of duration and speed, let alone far enough to make use of the "-5% per every 300 miles". So, which part is the broken/incorrect one? is the duration supposed to be in some other time frame? is the speed supposed to be faster? Is the range listed too far?
I tend to think the last one not a serious possibility, given the amount of other things that refer to such distance, but what says the community?
