Basically, does the Greensting Slayers Archetype Sneak Attack make the character eligible for Accomplished Sneak Attacker.
I've often heard that the class feature must bear the same name, but given some Nature Bonds and Animal Companion issues that may not be the case.
One more thing, it does state that the sneak attack damage dice may not exceed half your character level (rounded up), is that an ex nunc or ex tunc kind of deal?
An example: Say you're a rogue 1, warrior 2. On your third level you pick up ASA. On your 4th level you take a level in Alchemist, with the Vivisectionist Archetype.
Are you now level 4 with 3d6 sneak attack, or does feat retroactively deactivate itself until it meets the proper conditions again? Or is it even gone forever?
your supposed character actually has only 2d6 sneak attack since the vivisectionist and rogue levels stack together to determine how much rogue sneak attack you have.
But the answer to your question is you need to qualify for a feat to take it, and then you need to qualify for the feat to use it. If you have 13 str, take power attack, and then take off your str belt you can't use power attack until your str is 13 again. Same here. If you have to much sneak attack from your class then the feat would stop working.
That would imply that once you level up to 5, it would reactivate?
And what about the Greensting Slayer qualifying for ASA?
That would imply that once you level up to 5, it would reactivate?
6. Accomplished Sneak Attacker puts the limit at half your character level, so to be eligible for 3 dice, you need to be 6 (even if rogues and the like get it at odd levels).
And what about the Greensting Slayer qualifying for ASA?
You don't have the Sneak Attack class feature with the Greensting Slayer. At the same time, though, it does not count against how many dice your Sneak Attack has for the purposes of ASA.
Your number of sneak attack dice cannot exceed half your character level (rounded up).
5/2 = 2.5, rounded up that's 3.

You don't have the Sneak Attack class feature with the Greensting Slayer.
We've been over this countless times already. An ability does not need to have the exact name to satisfy a prerequisite as long as it specifies it works as that ability.
The Greensting Slayer arcane pool explicitly references the Rogue's Sneak Attack so per se it would satisfy the prerequisite, the point of contention might be that because it's a version that needs to be activated it might not count as a permanent ability.
In Pathfinder you never round up, 2.75 rounds to 2.
This is one of those weird cases where you do.The feat is for those who don't have much Sneak Attack. It shuts itself off too much for those close to full rogue levels.
the feat specifically says you round up.
