[QUOTE="logopolis, post: 4507983, member: 74341"] I was flipping through some 4E skills and feats the other day, and I noticed the Agile Athlete feat (roll d20 twice for Acrobatics or Athletics checks). Clearly this was a Paragon feat because it boosted two skills, but just how much of a boost was it compared to, say, Skill Focus? Would the feat still be good if just boosted one of those skills? Being a bored math geek, I decided to crunch the numbers and find out. As it turns out, rolling twice is [I]really [/I]good! Assuming that a typical challenge for the players (skill checks, monster defenses, etc.) has a 40-60% chance to be overcome at equal levels, rolling twice is equivalent to about +5 on your die roll.
