How many Goblins did you need to kill for Summon Goblin item ?

[Brother MEX]

I killed a few more on the way back to the FAT Cockobo, and currently killed 999 Goblins until now !
I also killed 255 Domovoi & 239 turtles, which is important as I was farming in the Antlions Cave ( immediatly outside the SAVE POINT ! ) SOLO with Edge, as I am currently grinding him to the same level as the rest of my party.

I didnt use sirens and first started near Baron until I got the Summon Cockatrice item
( killed 144 Helldivers until now and some others which drop the Summon Cockatrice item )

Now I am on the way to the place in Lodestone Cavern where I can farm Mindflyers ... currently killed 158 of them until now and reached the level of the other party members.

I recommend you to buy siren 99 pieces and save game before come in antlions cave and use siren until it 0 , if goblin not drop you can restart form save.
I use this method and reset for 4 round until goblin drop, and use this method with mindflay too. For mindflay I reset game for 3 round (about 370 siren).

Until now I cant buy siren, as I just defeated Rubicante !

As I was grinding Edge to the same level as the other party members BEFORE advancing to Rubicante, I had used that opportunity to farm Summon Goblin item in the Antlion Cave before advancing to farm Summon Mindflayer item in the Lodestone Cavern. I got Summon Cockatrice item near Baron very early when I started to farm for Summon Goblin item near Baron.

Even without sirens it is easy to farm Summon Goblin item just in front of the entrance to the SAVE point in Antlions cave. You only encounter either a single turtle OR a group of 3 Goblins with a Domovoi ( which doesnt drop the Summon Goblin item ! ) in the last row, which is killed last in AUTO-battle.

As I only wanted to grind levels for Edge, I had used Rydias STONE black magic to petrify anyone else

I got extremely lucky and got it on maybe my 3rd (or so) goblin kill at the very beginning of the game.

I wasn't even farming for it (I was just grinding a few levels for Kain & Cecil) and didn't even realize how lucky I was at the time (I hadn't yet looked up the drop rates for the extra summons until later).
