NethlingAt some point he was an Ooze but then we remembered that is just our misinterpretation of his shape-shifting abilities. He's a Construct since he's built from a plane and the shapeshifter ability is clearly described in his racial abilities. Perhaps the Ooze type could be acquired through a Species feat?
SpellwardYes, you can carry for a friend but cannot use. If you use or keep them as a Prize, you lose the benefits of this feat. We'll clarify that.
Legacy featsWe followed the format for Legacy feats already established in FC.
Arcane LoopYou may only cast a spell that you know but we'll look into this again.
Equilibrium We have a high AD traffic on our sessions. The GM grants a lot of bonus ADs and we spend a lot. So it all depends on someone's style of playing. Regardless, we'll look into this one again.
Mechanoid Ally and Dead Ally.Where the Type of the NPC is restricted (eg. Animal Partner) can you use these?
Yes, you can.
Do these feats add or replace the NPC’s original type?
They Add.
Do these feats add these templates in addition to the usual xp limit of the NPC.
Yes, they do.
Mind GateBreakdown is a physical manifestation of a psychological breakdown.
We'll note that. I don+'t think we ever described what it looks like other than that the surrounding NPCs all start wailing in pain, they get nose/ear bleeding, head buzzing/pain, feel sorry for being ever born, etc.
Thank you for the praise on Alignments as prerequisites. Everything you mentioned is exactly the reason I wrote so many feats for each Alignment. I aimed at 5 feats for each Alignment. We wanted to have 6 (or even 9!) but there's a limit at how much philosophical articles I can read or lectures I can listen to in a given timeframe

Also, we wanted to add glimmerrat's (Mark Newman's) Planescape feats but he didn't give us the green light (yet)
Planar CallYou can summon just about any NPC as long as you meet the Reputation Cost prerequisite. I believe the spell had a saving throw in an earlier incarnation but I an glimmerrat agreed it should be removed since it's a 9th level spell, has a high reputation cost and God knows what will happen once the summoned NPC arrives
Rain of FireYeah, everybody likes this spell
Lens/scopesYeah, we shall note that. Thanks!
Sickle of lightI believe these items are from the Warriors of Heaven. I'll have to double-check them.
ChocolatesThey can come in all flavors and shapes
OrganizationsYes, we will mention that.
Thanks again for your very insightful comments.
