House Rule Aid Another
Normally, a player may attempt to “aid another” on a skill check. The check would be DC 10 and, if successful, the player would grant a +2 bonus on his or her skill check.
You may choose to “aid another” to add a bonus greater than +2. The final DC is 5 x Modifier. So, to provide a +2 would still be DC 10, but to provide a +5 would be a DC 25 skill check.
Note: in order to add a bonus greater than +2, you must have at least one rank in the skill.
Note: for every five points by which you fail to meet the target DC, you actually impede the primary player’s progress, subtracting one from the player’s result.
