IOrb of Imposition: Once per encounter, after a save is rolled, you may apply a penalty to that save equal to your wisdom modifier.
Yeah. That's fair and easily the best fix. Don't get me started that the wand power is a single attack roll and the orb is every save; before we even consider the differences in Save vs. Defense scaling.
Player’s Handbook:
Class Powers/Features:
Seal of Binding (Cleric Daily 25): You can sustain this power no more than three times.
(This combos with a Demigod’s Divine Regeneration to kill almost anything, and taking an opponent out of the fight for many rounds can be too good on its own)
Come on, Divine Regen is clearly the issue here. Demigod is one of the most powerful epics without even considering it (back from the dead is low level, +2 to two scores is the standard for 'Always On' bonuses, level 30 is a know potential gamebreaker). Divine regen should just be ability
modifier regeneration, and allowed to stack with regeneration from any single other source.
All +2/+4/+6 damage items: Encounter Power, add a +5 item bonus to damage. This can actually come ahead in some cases for builds that have some but not many area attacks, but I think that's cool (choosing to use it at the right time is way more interesting).
I've mentioned my personal armor fixes in a separate thread and I'm happy with the results. Hide Armor Expertise needs to die and a lot of other builds need to have their AC scaling fixed.
Whirling barbs shouldn't get Barbarian Agility, most likely.
Two-weapon rangers shouldn't get prime shot. An old one, but still a good fix.
The 'feat tax' feats are such a huge can of worms I don't want to even start talking about them, but they're on 'The List' of things most DMs who really care will want to fix, somehow.
Dragon is, likewise, a huge can of worms and things in there tend to be all over the place. Wonder what I could do with that feat that grants your con bonus to AC with a minor for a fighter + hide expertise at epic...
