No buffs, no warg, no falcon, Flying Galapagos' bonus to Auto-Blitz damage is the same with or without falcon.
Damage variance between Dummy and Zombie Slaughter / Kasa / Salamander:
On some (maybe all) Althea Field maps, 2nd/Transcended job skills do official damage for some reason. (Only the Admin can tell us why)
On other maps such as abbey02/thor_v03, 2nd/Transcended job skills do the "adjusted" damage that compensates for higher HP/SP rate of the server.
Using your damage, it is not off by a factor of 10, but rather 8.1. (306 * 8.1 = 2478.6)
As for the reflect, I'm assuming you are wearing an item that auto-casts a magical or physical attack? Which is reflected by Kasa/Salamander
I tried going for myself and did not get reflected attacks.
