Assassin changes and class ability items idea

[Savagefool]

Can we please make the imp invis that assassins cast either longer duration based on assassin level (increase of caster level) or undispellable. The reason is for balance, assassins miss out on epic dodge in comparison to rogue and so there’s not much choice to move into assassin (especially as rolling a 1 isn’t an automatic failure so the death attack doesn’t stun anymore). Or the imp invis gives 60% (30 effective from blind fight) instead of 50, just a little buff hehe.

Same for ethereal visage, duration and caster level, would be nice to add a little buff to that, maybe natural dr?

Tying into that, the second suggestion is for items to modify class specific abilities:
e.g.
rage or thundering changes to balance barb (hatred stone?)
Additional favoured enemies for epic ranger (wanderers stone?)
Ability to use aa enchancement for xbows or slings (archers eye?)

You get the idea. Shifter suggestions/ideas coming soon!
Thanks for reading!
