Table Rules
In addition to the normal 5e rules:
Flanking
5e has flanking as an optional rule, but normally suggests advantage. This results in an average of +5 to the roll. This unbalances the game in favor of always rushing to flank above all. In order to maintain flanking as a tactical advantage without unbalancing the game in favor of flanking, we will use a +2 when flanking with an ally (this includes summons, pets, and allied npcs).
