Baldur's Gate : The Sword Coast Chronicles : NWN2 Persistent World

My ranger has 7 attacks at this point, 4 mainhand and 3 offhand. When I activate Athkatlian I lose all four of my mainhand attacks and get +4 damage/ac on my offhand. I have relogged, and it switched to +1damage/ac with 3mainhand 3 offhand attacks, but as soon as I transitioned it went back to removing all of my mainhand attacks. When I relogged again it fixed nothing.

I think this is a bug? Id assume so at least. Losing all my mainhand attacks kind of makes the feat worthless.

the main hand attacks are always the one's lost. This applies to Northlander Hewing, Athkatlan Triparite, and Sembian Fencing (I don't think there are any other feats that reduce attacks, but I believe this applies across the board). My understanding from previous discussions with Rasael and Valefort is that this is just how NWN2 does it and part of that black box/core code that we can't touch.

Yeah. I might be wrong, but from where I read elsewhere I thought Athkatlian Triparite ignores the offhand completely and is meant to only take attacks off the mainhand after the first three, so at 16 BaB, Atkatlian Triparite takes aways only the 1 bab attack leaving the 16/11/6 and adding 1 AC and Damage, no matter if you are using an offhand or not. If Im wrong thats ok, just means I wont be using the feat for quite a bit longer.

Yes to both.
