So, is blitz meant to be a constant buff? But, not measure the foe & killer?
Giving assassinate chance to every 20 roll may be over-power. I think Sneak Attack crit on crit is proper for Lethality enhancement.
Yup, squishy, but deadly. I think the best mitigation method for rogues are using their GUTS & WIT
I like to see more aggro management methods(Bluff, Diplo, sometimes Intim) & some roguish CC(SAP, hamstring, slicing blow) here.
It's really too hard to get enough social skill points for harder EE contents like stormhorn. Even with full skill point to social skill, +20 bluff, diplo gear, some extra cha gears doesn't make much difference on harder EE contents. It seems just always fail on that social skill check whether you fully invested for it or not.
Defensive roll & slippery mind are the last bastion for squishy rogues. It should let rogues narrowly escape brushes with death like its description.
Sadly, it's currently not. I think granting some temporary hp & dodge on successful reflex save would be helpful for that emergency situation. Also, granting some additional will save on 2nd roll for slippery mind, too.
Threshold for defensive roll should be raised.
-----------------------------
I like to add something here.
Let assassins use hide skill to keep sneak state like concentration skill for casters.
It's very annoying to lose assassination chance by just 1 single weak arrow. Even missed or dodged arrow can break sneak.
Casters & Divines can cast in heavy rain of arrows,
but even if that arrow deals just 1 damage,
it can be enough to break well skilled master assasin's assasination chance.
Casters & divine can use even no fail casting with quicken.
