I have found 3 so far in the game. Does anybody know the location of the last 2? There is 5 in total correct?

which ones did you find?

So far I've found 3 as well

1 was in esto erza pyramid

1 was is crescent rivulet

1 was either on a mountain or in the underground area. Can't remember 

Relics Found So Far

1. Crescent Rivulet

•Relic found here.

•Confirmed by both of us.

2. Underground Snow Forest

•Located shortly after meeting the Dwarf King.

•From the first intersection, take the west path.

•The relic is hidden along that route.

3. Floating Cave (Wind Fiend Area)

•In the last map where there are multiple rooms with stairs leading downward.

•The relic is located in the northwest corner of the map.

•Easy to miss because the mist obscures it until you get very close.

Relics Mentioned but Not Yet Confirmed

4. Esto Era Pyramid

•You mentioned there is supposed to be a relic here.

•I haven't found this one yet.

•Do you remember roughly where in the pyramid it is?

5. Mountain Area

•There may be a relic in the mountains.

•However, it's possible this is actually the same relic as the Underground Snow Forest one mentioned above.

•Not sure if they're separate locations or if we're talking about the same relic.

Current Count

Confirmed relics:

1.Crescent Rivulet

2.Underground Snow Forest

3.Floating Cave (Wind Fiend area)

Possible additional relics: 4. Esto Era Pyramid 5. Mountain area (may be the same as #2)

Too bad there doesn't seem to be any way to check how many relics your character is currently carrying.

two things

1. I believe I am thinking of that place you mentioned as the mountain 

2. I found one in garamonde village in fused world surrounded by swamp on right side in a forest path

3. Found 1 wild temple top left

Off topic but it's Bosch.

Does his procure actually useful? I tried him but his procure just do random stuff. :/

Or will Procure be better after collecting all the relics?

found one in the ancient castle in one of the prison i think right door

I also think he rotates the number of relics that you have found thus far. I'm not seeing any repeated animations at all. Can somebody confirm this?
