Instance-Based Gaming

*"Damage"/"Damage roll" modifiers can only be applied once per target per power by a given character during said character's turn.  These modifiers still apply on any damage/damage rolls the character is directly responsible for when it is <u>not</u> said character's turn (e.g. opportunity attacks, 'out-of-turn' attacks from allies, the secondary damage roll of <i>dire radiance</i>, etc.), but the once per target per power rule is still in effect (so if you used twin strike as an OA, you'd still only apply damage roll modifiers once, for each use of twin strike in that manner).  This houserule is meant to curb excessive 'multiattack' abuse from a lone character, and brings the ranger in line with other melee strikers, such as the barbarian and the rogue.

*All increases to a character's critical threat range which are not temporary (such as from a power effect) are capped at 19-20.  Permanent 18-20 critical threat ranges (or larger) no longer exist.  In addition to this, all feats which increase critical threat ranges are banned.  Instead, at 21st level, all of your attack rolls score a critical hit on a result of 19-20.
