I would love to see anarchic and chaotic lines of crafting added to the GS crafting system. They would work in the same fashion as good/evil lines with an expanded list of tier 2/3 powers. Some possible tier 3 combo shard effects could be...
good/chaos equip: Essence of Freedom- This power grants a permanent Freedom of Movement effect to the user and also prevents the user from being banished.
evil/law equip: Rule of the Tyrant - On any hit there is a chance that dominate monster is cast on your attacker DC 35.
good/law weapon: Righteous Fury - This weapon bypasses all bypassable DR except DR X/-, DR X/epic, and DR X/good. It also inflicts 3d6 extra good damage against any evil creature it hits.
chaotic/evil weapon: Ravager - This weapon does 6d6 extra untyped damage per hit and inflicts 2d6 untyped damage on the wielder per hit. Additionally, their is a small chance for the wielder to enter into a death frenzy (as FB ability) per hit.
chaos/chaos weapon Unpredictable Surge - On any hit there is a chance for this weapon to manifest any number of tier 3 GS weapon powers. Additionally, this weapon randomly gains the ability to bypass a specific type of DR or an additional weapon damage effect on any hit.
chaos/chaos equip Unpredictable Surge - Any time the user is hit there is a small chance for any number of random powers to be triggered. (Full list of GS tier 3 equip effects, guard effects, and anything that a potion of wonder or the wild mage belt clickie can cast).
law/law equip: Stasis - While this item is equipped no new spell effects with durations may be applied to you nor can you be effected by any dispelling or disjunction effect. Instant spells still effect you normally.
chaos/air weapon: Tornado - On any hit there is a small chance that your target is buffeted by Tornado force winds. (~300 bludgeoning damage and the air guard knockdown effect). Same thing on equip except a guard effect.
chaos/fire weapon: Inferno - On any hit there is a small chance that your target is engulfed in flames. (~300 fire damage a tick for 5 ticks unless they are hit with a heal spell, cold effect, or merman's charm).
law/fire weapon: Righteous Flame - On any hit there is a small chance that your target is hit with a blast of holy flames. (~200 lawful damge + ~200 fire damage).
